Embodiment
Below with reference to accompanying drawings exemplary embodiment of the present disclosure is described in more detail.Although show exemplary embodiment of the present disclosure in accompanying drawing, however should be appreciated that can realize the disclosure in a variety of manners and not should limit by the embodiment set forth here.On the contrary, provide these embodiments to be in order to more thoroughly the disclosure can be understood, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
Fig. 1 shows a kind of according to an embodiment of the invention flow chart of data download method.As shown in Figure 1, the method comprises:
Step S110, sends the request of downloading new data, the data that reception server returns to server.
In one embodiment of the invention, the request of the download new data that this user end to server sends comprises: the data number that request is downloaded, and has downloaded to the mark of the up-to-date data in database.Like this, server end thinks that the data that client is asked are from the current up-to-date data of data to the Data Identification comprised described request of server end, and the data number of request is the number comprised in described request.Here, the generation time of data that what " newly " and " old " compared is, " newly " is the posterior data of generation time, and " old " is generation time data formerly.
Step S120, judges whether the data that server returns can be connected with the data with existing in database, if perform step S130, performs step S140 if not.
In one embodiment of the invention, be judged as being connected when the number of the data that server returns is less than the data number of request download, be judged as divergence when the number of the data that server returns is more than or equal to the data number of request download.This is because the data number that the request comprised in the request of download new data that sends with client of server end is downloaded, and download to the result being designated the foundation of return data of the up-to-date data in database.
Increase progressively successively for the sequencing of the mark of data according to its generation time: what client had downloaded to up-to-date data in database is designated 1000, current request 20 data.If when received server-side is to the request of client, the mark of up-to-date data of server end is to 1050, then server can return to client 20 data being designated 1031 ~ 1050, and client can be judged as divergence.If when received server-side is to the request of client, the mark of up-to-date data of server end is to 1015, then server can return to client 15 data being designated 1001 ~ 1015, client can be judged as being connected.
Step S130, the data returned by server are saved in database, and the show tags of the data this returned is set to effectively.Perform step S150.
Step S140, it is invalid that the show tags being effective data by show tags existing in database is all set to, and then the data that server returns is saved in database, and the show tags of the data returned by server is set to effectively.Perform step S150.
Step S150, the show tags only in display database is effective data.
In technical scheme shown in Fig. 1, asking after new data, all judge whether new data and existing data are connected at every turn, then illustrate that when divergence data create tomography, by arranging and the show tags of service data, and only show up-to-date continuous print data when showing, such user sees that data are continuous print data, wherein there is not layer data, solves user thus 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 by being saved between the fault zone corresponding with the layer data of divergence and gathering between safeguarded fault zone.Be specially: the mark of the oldest data in the data returned with server and the mark of up-to-date data downloaded in database form one and represent array between fault zone, and this array are saved in the array set representing and gather between fault zone.Such as, what downloaded to up-to-date data in database with aforesaid client is designated 1000, current request 20 data, when received server-side is to the request of client, the mark of up-to-date data of server end is to 1050, server returns 20 data instances being designated 1031 ~ 1050 to client, for array is [1031,1000] between the fault zone that the layer data of this divergence is corresponding.Between fault zone, two end-point datas 1000 and 1031 of [1031,1000] are not included in layer data, and namely corresponding layer data is 1001 ~ 1030.
For making technical scheme of the present invention clearly, below technical scheme of the present invention is further described.
Fig. 2 shows the flow chart of data download method according to an embodiment of the invention.Fig. 3 shows the data variation schematic diagram of client in data downloading process according to an embodiment of the invention.Be described the method shown in Fig. 2 below in conjunction with Fig. 3, as shown in Figure 2, the flow process of a client-requested new data comprises:
Step S202, user end to server sends the request of downloading new data.
In one embodiment of the invention, the request of the download new data that this user end to server sends comprises: the data number that request is downloaded, and has downloaded to the mark of the up-to-date data in database.
First, client need be determined will " ask download data number ", as being generally 20.In addition, client also needs the mark of the up-to-date data obtaining (namely having downloaded in client database) in data with existing, as the lines 310 in Fig. 3.Above-mentioned " the data number that request is downloaded " and " marks of the up-to-date data in data with existing " are saved as a variable for subsequent use.Then, " the data number that request is downloaded " and " marks of the up-to-date data in data with existing " are spliced into a URL, to the data of server request down loading updating by client.
Step S204, the data that client reception server returns.
Here, server can judge to return how many record certificate according to " marks of the up-to-date data in data with existing ", and returns which data.Under normal circumstances, " marks of the up-to-date data in data with existing " form of expression is on the server " request is to this Data Identification " (as lines in Fig. 3 310), also be, the interval obtaining the scope of data is " the just infinite mark to the up-to-date data in data with existing ", formula is: (∞, the mark of the up-to-date data in data with existing), do not comprise the data specified by mark of the up-to-date data in this data with existing within the scope of it.Meanwhile, " the data number that request is downloaded " also will limit as a kind of condition, and namely server end " the data number returned " is less than or equals this restriction.Finally, the condition of the return data of server end is: one, the number of return data is less than or equals " the data 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 whether the data number that server returns is less than or equal to 0, is perform step S208, otherwise performs step S210.
Step S208, if the data 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 upgrade, client is the latest data on server to the latest data in user's reminder-data storehouse, without the need to asking, transmitting procedure stops again.
Step S210, if the data number that server returns is greater than 0, then represent that server end has the data also newer than the latest data of client, therefore continue to judge whether the data that server returns can be connected with the data with existing in database, be specially judge data number that server returns whether be less than ask the data number downloaded, be perform step S212, otherwise perform step S214.
Step S212, if the data number that server returns be less than ask download data number, then represent that the data that server returns can be connected with the data of client this locality, the data that server returns by client are saved in database, and the show tags of the data this time returned by server is set to effectively.Such as, in one embodiment of the invention, be inserted in database by the data that the SQL statement of an INSERT can realize server to return.Process ends.
Step S214, if the data number that server returns be more than or equal to ask download data number, then represent that the data that server returns can not be connected with the data of client this locality, there is layer data, then client will to be saved between safeguarded fault zone in set between the fault zone that this layer data is corresponding.
In one embodiment of the invention, the identification record of the oldest data in the data that first server returns by client gets off, and saves as a variable, in the present embodiment, can be described as " marks of the oldest data in server return data ", as shown in lines in Fig. 3 320.Then, client, by " marks of the up-to-date data in data with existing ", as shown in the lines 310 in Fig. 3, saves as a variable, for subsequent use.Subsequently, from database, take out " the interval set of tomography " (as in Fig. 3, have between two fault zones, place and be labeled as 331 and 332 respectively, then these two is exactly " the interval set of tomography " altogether)." gather " range intervals being mainly used to record each tomography between fault zone, these tomographies all also do not download in client, but again can to server request when client needs.And the object of taking out " gathering between fault zone " will be added between new fault zone in this set.
In one embodiment of the invention, the array list ArrayList in JAVA class libraries is adopted to realize gathering between fault zone.And be by SQLite statement, set between fault zone is taken out specific to the way in Android client.Bytes type (also between available characters string descriptor fault zone) due to what take out, client can pass through unserializing technology (de-serialize), also be the readObject method of the ObjectInputStream class of Android, this record be converted into an ArrayList object.And in the middle of ArrayList, each is all made up of the one-dimension array of Integer, each array has two elements, is used for two borders represented between this fault zone respectively.What client will be done is as the border of two between fault zone using previously mentioned " marks of the oldest data in the data that server returns " and " marks of the up-to-date data in data with existing ", insert in the one-dimension array of new Integer respectively, then added in ArrayList object, finally, be a Bytes object by its serializing (serialize) again, also be the toByteArray () of the ObjectOutputStream of Android, finally, then deposited back in the middle of database.So far, gather between many new fault zones between fault zone, 333 in Fig. 3 is between this fault zone newly increased.
Step S216, it is invalid that the show tags being effective data by show tags existing in database is all set to.
Value by data existing in client (data segment 311 as in Fig. 3) show tags changes 0 (hiding) into from 1 (display), to guarantee that the data with existing section 311 before tomography 333 can not be presented in the display interface of client.Specific practice is: by a SQL statement, changes the value of the show tags of all data with existing into 0 (hiding) from 1 (display).
Then the data that server returns are saved in database by step S218, and the show tags of the data returned by server is set to effectively.
Those data 333 returned by server end before can all be inserted in database by client, and the value of its show tags is set to 1 (display).So far, whole transmitting procedure terminates.
From above-mentioned, in technical scheme of the present invention, by arranging and safeguarding show tags, only show up-to-date continuous print data, such user sees that data are continuous print data, have recorded in addition between fault zone, like this when user thinks request layer data, can according to the corresponding layer data of tomography interval requests of record.
