Detailed description of the invention

It is more fully described the exemplary embodiment of the disclosure below with reference to accompanying drawings.Although accompanying drawing showing the exemplary embodiment of the disclosure, it being understood, however, that may be realized in various forms the disclosure and should do not limited by embodiments set forth here.On the contrary, it is provided that these embodiments are able to be best understood from the disclosure, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.

In the solution of the present invention, the process every time downloading new data is safeguarded the display labelling of data and recorded tomography interval, afterwards when layer data downloaded by needs, according to the corresponding layer data of tomography interval requests recorded, and safeguard the display labelling of data so that what show is all up-to-date continuous print data always.Below it is divided into two large divisions that the technical scheme of invention is illustrated: request new data and request layer data.

One request new data

Fig. 1 illustrates the flow chart of a kind of according to an embodiment of the invention new data method for down loading.As it is shown in figure 1, the method includes:

Step S110, sends the request downloading new data to server, receives the new data that server returns.

In one embodiment of the invention, the request downloading new data that this user end to server sends includes: the new data bar number that request is downloaded, and the mark of the up-to-date data having been downloaded in data base.So, server end thinks that the requested data of client are from server end currently up-to-date data data to the Data Identification comprised described request, and the data strip number of request is the bar number comprised in described request.Here, what " newly " and " old " compared is the generation time of data, and " newly " is generation time posterior data, and " old " is generation time data formerly.

Step S120, it is judged that whether the new data that server returns can be connected with the data with existing in data base, if performing step S130, performs step S140 if not.

In one embodiment of the invention, during the new data bar number that the bar number at the new data that server returns is downloaded less than request, it is judged as linking, during the new data bar number that the bar number at the new data that server returns is downloaded more than or equal to request, is judged as divergence.This is because the data strip number that the request comprised in the request downloading new data that sends with client of server end is downloaded, and the up-to-date data having been downloaded in data base be designated the result of foundation returning data.

Example it is incremented by successively according to its sequencing producing the time: what client had been downloaded into the up-to-date data in data base is designated 1000, current request 20 data with the mark of data.If received server-side is to the request of client, the mark of a up-to-date data of server end is to 1050, then server can return, to client, 20 data that be designated 1031～1050, and client can be judged as divergence.If received server-side is to the request of client, the mark of a up-to-date data of server end is to 1015, then server can return, to client, 15 data that be designated 1001～1015, and client can be judged as linking.

Step S130, is saved in the new data that server returns in data base, and is set to effectively by the display labelling of the new data of this return.Perform step S150.

Step S140, is labeled as display existing in data base the display labelling of effective data and is set to invalid, be then saved in data base by the new data that server returns, and the display labelling of the new data returned by server is set to effectively.Perform step S150.

Step S150, the display in a video data storehouse is labeled as effective data.

In technical scheme shown in Fig. 1, after new data, all judge whether new data and existing data are connected in request every time, then illustrate that when divergence data create tomography, by arranging and safeguard the display labelling of data, and only show up-to-date continuous print data when display, such user sees that data are continuous print data, is wherein absent from layer data, thus solves user and can not know the problem that whether there is layer data in shown data.

When method shown in Fig. 1 can also be judged as divergence in the step s 120, further the tomography interval corresponding with the layer data of divergence is saved in the tomography interval set safeguarded.Particularly as follows: mark and the identifying of a up-to-date data having been downloaded in data base with the oldest data in the new data of server return form an array representing that tomography is interval, and this array is saved in the array set that expression tomography interval is gathered.Such as, it is designated 1000 with what aforesaid client had been downloaded into a up-to-date data in data base, current request 20 data, when received server-side is to the request of client, the mark of a up-to-date data of server end is to 1050, server returns to client and is designated 20 data of 1031～1050 is example, and the tomography interval that the layer data of this divergence is corresponding is array is [1031,1000].Two end-point datas 1000 and 1031 of tomography interval [1031,1000] are not included in layer data, and namely corresponding layer data is 1001～1030.

For making technical scheme clearly, below technical scheme is further described.

Fig. 2 illustrates the flow chart of data download method according to an embodiment of the invention.Fig. 3 illustrates the data variation schematic diagram of client in data downloading process according to an embodiment of the invention.Below in conjunction with Fig. 3, the method shown in Fig. 2 is illustrated, as in figure 2 it is shown, the flow process of a client new data of request includes:

Step S202, user end to server sends the request downloading new data.

In one embodiment of the invention, the request downloading new data that this user end to server sends includes: the new data bar number that request is downloaded, and the mark of the up-to-date data having been downloaded in data base.

First, client need to determine will " ask download new data bar number ", as being generally 20.Additionally, client also needs to obtain the mark of a up-to-date data of (namely having been downloaded in client database), the lines 310 in Fig. 3 in data with existing.Above-mentioned " the data strip number that request is downloaded " and " mark of the up-to-date data in data with existing " are saved as a variable standby.Then, " the data strip number that request is downloaded " and " mark of the up-to-date data in data with existing " are spliced into a URL by client, to the data of server request down loading updating.

Step S204, client receives the new data that server returns.

Here, server can judge to return how many data according to " mark of the up-to-date data in data with existing ", and returns which data.Under normal circumstances, " mark of the up-to-date data in data with existing " form of expression on the server is " request is to this Data Identification " (in Fig. 3 lines 310), namely, the interval of the scope obtaining data is " mark of a just infinite up-to-date data in data with existing ", formula is: (∞, the mark of the up-to-date data in data with existing), what do not include the up-to-date data in this data with existing within the scope of it identifies specified data.Meanwhile, " the data strip number that request is downloaded " also will as a kind of condition restriction, and namely server end " the data strip number of return " is less than or equal to this restriction.Finally, the condition of the return data of server end is: the bar number one, returning data is less than or equal to " the data strip number that request is downloaded "；Two, the scope obtaining data is (∞, the mark of the up-to-date data in data with existing), and two conditions become the relation of "AND".

Step S206, client judges that whether new data bar number that server returns is less than or equal to 0, is then execution step S208, otherwise performs step S210.

Step S208, if the new data bar number that server returns is less than or equal to 0, then represent that up-to-date Data Identification in client has been that the latest data of server end identifies, namely the data of client have been up-to-date, the data that server end does not update, client prompts the user with the latest data that the latest data in data base is on server, it is not necessary to ask again, and transmitting procedure terminates.

Step S210, if the new data bar number that server returns is more than 0, then represent the data that server end is existing also newer than the latest data of client, therefore continue to judge whether the new data that server returns can be connected with the data with existing in data base, it is specially and judges that new data bar number that server returns is whether less than the new data bar number of requested download, it is then perform step S212, otherwise performs step S214.

Step S212, if the new data bar number that server returns is less than the new data bar number of requested download, then represent that the data that server returns can be connected with the data of client this locality, the new data that server returns is saved in data base by client, and the display labelling of the new data this time returned by server is set to effectively.Such as, in one embodiment of the invention, the data that can realize server returns by the SQL statement of an INSERT are inserted in data base.Process ends.

Step S214, if the new data bar number that server returns is more than or equal to the new data bar number of requested download, then represent that the new data that server returns can not be connected with the data of client this locality, there is layer data, then the tomography interval corresponding in this layer data is saved in the tomography interval set safeguarded by client.

In one embodiment of the invention, the identification record of the oldest data in the data that first server is returned by client gets off, and saves as a variable, in the present embodiment, can be described as " mark that server returns the oldest data in data ", in Fig. 3 shown in lines 320.Then, client is by " mark of the up-to-date data in data with existing ", shown in the lines 310 in Fig. 3, saves as a variable, standby.Subsequently, from data base, take out " the interval set of tomography " (in Fig. 3, having two tomography intervals, place to be respectively labeled as 331 and 332, then the two is exactly " the interval set of tomography " altogether)." set of tomography interval " is mainly used to record the range intervals of each tomography, and these tomographies all have not yet been downloaded in client, but again can to server request when client needs.And take out " set of tomography interval " be intended to that to add new tomography in this set interval.

In one embodiment of the invention, the array list ArrayList in JAVA class libraries is adopted to realize the set of tomography interval.And be by SQLite statement, the set of tomography interval is taken out specific to the way in Android client.It is Bytes type (also available characters string descriptor tomography is interval) due to what take out, client can pass through unserializing technology (de-serialize), namely the readObject method of the ObjectInputStream class of Android, this record is converted into an ArrayList object.And in the middle of ArrayList, each item is all made up of the one-dimension array of Integer, each array has two elements, is respectively intended to represent two borders that this tomography is interval.Client to do is to previously mentioned " marks of the oldest data in the data that server returns " and " mark of the up-to-date data in data with existing " two borders as tomography interval, it is respectively filled in the one-dimension array of new Integer, then it is added in ArrayList object, finally, being serialized (serialize) again is a Bytes object, namely the toByteArray () of the ObjectOutputStream of Android, finally, then be stored back in the middle of data base.So far, the set of tomography interval is by interval for many new tomographies, and 333 in Fig. 3 are this tomography newly increased interval.

Step S216, display existing in data base is labeled as the display labelling of effective data be all set to invalid.

Show that by data existing in client (data segment 311 in Fig. 3) value of labelling changes 0 (hiding) into from 1 (display), will not be shown in the display interface of client with the data with existing section 311 before guaranteeing tomography 333.Specific practice is: by a SQL statement, change the value of the display labelling of all data with existing into 0 (hiding) from 1 (display).

Step S218, is then saved in the new data that server returns in data base, and the display labelling of the new data returned by server is set to effectively.

Those data 333 returned by server end before can be inserted in data base by client, and is shown that the value of labelling is set to 1 (display).So far, whole transmitting procedure terminates.

From above-mentioned, in technical scheme, by arranging and safeguarding display labelling, only show up-to-date continuous print data, such user sees that data are continuous print data, additionally have recorded tomography interval, so when user thinks request layer data, it is possible to the corresponding layer data of tomography interval requests according to record.

Two request layer datas

Fig. 4 illustrates the flow chart of a kind of according to an embodiment of the invention method for processing layer data.As shown in Figure 4, the method includes:

Step S410, sends the download request of some layer datas of up-to-date continuous data in request next-door neighbour data base to server, receives the layer data that server returns.Wherein, process according to aforesaid request new data, data base preserves data, the display labelling of data and the tomography interval that be made up of the tomography interval corresponding with layer data downloaded gather, wherein the display of up-to-date continuous data is labeled as effectively, it is invalid that the display of other data is labeled as, and display is labeled as effective data and can be shown.

In one embodiment of the invention, the layer data that user end to server sends is downloaded request and is included: the oldest layer data bar number reading the mark of data, request download in the up-to-date continuous data in data base, and is close to the oldest mark reading data in the layer data corresponding to tomography interval of up-to-date continuous data.Specifically, tomography interval set in ergodic data storehouse, the tomography finding the up-to-date mark reading data in the layer data of correspondence and the oldest mark next-door neighbour reading data in up-to-date continuous data is interval, and this tomography interval is the tomography interval being close to up-to-date continuous data.Wherein, tomography interval is an array comprising two elements, first element in this array is the mark of the up-to-date data in this layer data corresponding to tomography interval, and second element is the mark of the oldest data in this layer data corresponding to tomography interval.

Step S420, it is judged that it is interval whether the layer data that server returns fills up the tomography being close to up-to-date continuous data, is then perform step S430, otherwise performs step S440.

In one embodiment of the invention, it is judged as filling up during the bar number of the layer data downloaded more than 0 and less than described request at the bar number of layer data that server returns, is judged as unfilled during the bar number of the layer data that the bar number at the layer data that server returns is downloaded more than or equal to described request.

Step S430, the layer data that server returns is inserted in described data base, the display arranging the layer data that server returns is labeled as effectively, and be set to effectively by the display labelling downloading data between next tomography interval interval for the tomography of interval for the tomography of up-to-date for this next-door neighbour continuous data and the described up-to-date continuous data of next-door neighbour, and the tomography deleting the up-to-date continuous data of described next-door neighbour from data base is interval.

Step S440, the layer data that server returns is inserted in described data base, the display arranging the layer data that server returns is labeled as effectively, and interval for the tomography of up-to-date for described next-door neighbour continuous data is represented the mark of a up-to-date data, the mark of the oldest data being revised as in the layer data of described return in this tomography interval.

So, by the method shown in Fig. 4, it is possible to obtain layer data according to the tomography interval recorded.Repeat the method shown in Fig. 4, it is possible to start in turn to obtain layer data from up-to-date continuous print data, fill up tomography interval, until having been filled up in all of tomography interval.

The condition of the flow process triggering a layer data download is generally: user sees that " the oldest data in up-to-date continuous print data " are (it is envisioned that be, when there is no network environment, user can read these continuous print data always, until touching the oldest one, perhaps start afterwards not plan a successor, perhaps there is no older data).At this moment, in order to ensure that old data can download and allow user see, it is necessary to download layer data to server request.Detailed process is as shown in Figure 5.

Fig. 5 illustrates according to an embodiment of the invention for processing the flow chart of the method for layer data.Fig. 6 illustrates that the layer data once downloaded according to an embodiment of the invention can fill up the schematic diagram that tomography is interval.Fig. 7 illustrates that the layer data once downloaded according to an embodiment of the invention can not fill up the schematic diagram that tomography is interval.Below in conjunction with Fig. 6 and Fig. 7, the method for processing layer data shown in Fig. 5 is illustrated.As it is shown in figure 5, the flow process of a client layer data of request includes:

Step S502, user end to server sends the request downloading layer data.

In one embodiment of the invention, the layer data that user end to server sends is downloaded request and is included: the oldest layer data bar number reading the mark of data, request download in the up-to-date continuous data in data base, and is close to the oldest mark reading data in the layer data corresponding to tomography interval of up-to-date continuous data.

For example, see Fig. 6: first, client, it is to be appreciated that the oldest mark reading data in up-to-date continuous data 644 in data base, the lines 620 in Fig. 6, is saved as a variable standby.Specifically can pass through SQL statement, obtain all of display and be labeled as 1 (display) and represent the mark that number is that minimum data.Meanwhile, client is it should also be understood that the layer data bar number that to ask altogether, it is assumed herein that the same with obtaining new data, disposable acquisition is less than 20 data, then, will " the layer data bar number of request download " to save as a variable standby.And then, client needs to obtain after " mark of the oldest data in up-to-date continuous data in data base ", back to back " tomography is interval ", hereinafter referred to as " tomography being close to up-to-date continuous data is interval ", tomography interval 655 in Fig. 6, namely lines 620 are to the part between lines 610.Still for android system, first pass through SQLite statement and tomography set is taken out, by its unserializing (de-serialize), then this record is converted into an ArrayList object.First element (element finally added) from ArrayList, this element is the one-dimension array of an Integer, represents one " tomography is interval ".Then, read should two boundary values of " tomography interval ", they lay respectively at first element of this array and second element.Here still with " article mark with successively decrease order from the new to the old " be arranged as example, first element is the mark of the up-to-date data in this layer data corresponding to tomography interval, and second element is the mark of the oldest data in this layer data corresponding to tomography interval.So, client just obtains call parameter during request layer data: " the oldest mark reading data in up-to-date continuous data ", " the layer data bar number that request is downloaded ", and " being close to the oldest mark reading data in the layer data corresponding to tomography interval of up-to-date continuous data ", three above parameter is spliced into a URL, initiate request to server, wait result to be returned.

Step S504, client receives the layer data that server returns.

Server can according to " the oldest mark reading data in up-to-date continuous data " and " being close to the oldest mark reading data in the layer data corresponding to tomography interval of up-to-date continuous data ", common judgement should return how many data, and returns which data.Under normal circumstances, " the oldest mark reading data in up-to-date continuous data " form of expression on the server is " starting from this data mark ", and the form of expression that " being close to the oldest mark reading data in the layer data corresponding to tomography interval of up-to-date continuous data " is on the server is " request is to this number of units Data Identification ", namely the interval obtaining the scope of data is the tomography interval 655 in Fig. 6, and in scope, do not include the data that this start-stop mark is specified.Meanwhile, " the layer data bar number that request is downloaded " also will as a kind of condition restriction, it is necessary to server end " the layer data bar number of return " is less than or equal to this restriction.Finally, the foundation returning layer data of server end is: one, the layer data bar number that the layer data bar number returned is less than or downloads equal to request；Two, the scope obtaining data is to start to " the oldest mark reading data being close in the layer data corresponding to the tomography interval of up-to-date continuous data " from " the oldest mark reading data up-to-date continuous data ", and both become the relation of "AND".Below the layer data that server end returns is designated 666.

Step S506, it is judged that whether the layer data bar number that server returns, less than or equal to 0, is then perform step S508, otherwise performs step S510.

Step S508, client prompts the user with does not have older data, process ends on server.

Step S510, it is judged that whether the layer data bar number that server returns, less than requested layer data bar number, is then perform step S512, otherwise performs step S518.

This step is judge whether the layer data that server currently returns fills up the tomography interval being close to up-to-date continuous data.If particularly as follows: the layer data of server return is less than the layer data bar number of requested download, then represent that tomography can be filled, as shown in Figure 6, the layer data 666 that server returns can fill up tomography interval 655, and tomography interval can directly be deleted from the set of tomography interval.Otherwise, if the layer data that server returns is more than or equal to the layer data bar number of requested download, then it represents that tomography can not be filled, as shown in Figure 7, the layer data 666 that server returns can not fill up tomography interval 655, it is necessary to reduces the scope that this tomography is interval.

Step S512, is inserted into the layer data that server returns in data base, and the display arranging the layer data that server returns is labeled as effectively.

Referring to Fig. 6, the layer data 666 that server returns is inserted in data base, just can fill up tomography interval 655.And the display labelling of the layer data 666 of insertion is set to effectively (being set to 1, display), namely newly downloaded data need display.

Step S514, the display labelling downloading data between the next tomography interval that the tomography of up-to-date for this next-door neighbour continuous data is interval and the up-to-date continuous data of this next-door neighbour tomography is interval is set to effectively.

In figure 6, download data between tomography interval 655 and its next tomography interval 677 are data block 633, it is set to effectively by the display labelling of data in data block 633, such data block 633, newly downloaded layer data 666 and former continuous data 644 constitute new continuous data, and all shown.

Specifically: client need to read " the oldest mark reading data being close in the layer data corresponding to tomography interval of up-to-date continuous data " and " position of tomography interval place ArrayList " (hereinafter referred to as " position of fault ") that preserve before, and the latter is mainly used to navigate to accurately in lists on that tomography interval.Then, client passes through ArrayList.get (position of fault+1), obtains the next tomography interval 677 after tomography interval 655 in this prior.Then, the mark of the up-to-date data in the layer data of interval 677 correspondences of acquisition tomography, and it is saved as a variable, standby.Finally, pass through SQL statement, client, by the display mark value of the data between " mark of the oldest data in the layer data of interval 655 correspondences of tomography " and " mark of the up-to-date data in the layer data of next interval 677 correspondences ", is revised as 1 (display) from 0 (hiding).So, tomography interval will be filled, and before tomography interval, existing article will be engaged on after layer data, until next tomography.

Step S516, the tomography deleting the up-to-date continuous data of this next-door neighbour from data base is interval.Process ends.

Specifically, in " ArrayList object ", delete the tomography being filled interval.

Step S518, is inserted into the layer data that server returns in described data base, and the display arranging the layer data that server returns is labeled as effectively.

Referring to Fig. 7, the layer data 666 that server returns is inserted in data base, tomography interval 655 can't be filled up.The display labelling of the layer data 666 of insertion is set to effectively (being set to 1, display), and namely newly downloaded data need display.Up-to-date continuous data now is made up of newly downloaded layer data 666 and former data 644.

Step S520, represents the mark of a up-to-date data, the mark of the oldest data being revised as in the layer data of described return in this tomography interval by interval for the tomography of up-to-date for this next-door neighbour continuous data.Process ends.

Referring to Fig. 7, before downloading layer data, up-to-date continuous data is 644, and the tomography interval being close to up-to-date continuous data is 655.After downloading layer data, up-to-date continuous data is the combination of 644 and 666, and the tomography interval being close to up-to-date continuous data is 688.So displayable expanded range, the tomography interval of next-door neighbour reduces.

Specifically, after the boundary value that the tomography having revised next-door neighbour is interval, ArrayList is put back in this tomography interval.In Android operation system, is Java programming language due to what adopt, and the array of buffer memory actually pointer type, namely " tomography of next-door neighbour is interval " object with in ArrayList to as if associate, therefore other operation need not be done.And in other languages, then it is likely to also need to be placed back into ArrayList and it needs to cover original object.So far, transmitting procedure terminates.

Repeat the flow process shown in Fig. 5 and can obtain layer data successively, until all of tomography interval is all filled.
