Fig. 1 shows a kind of flow chart of data download method according to an embodiment of the invention.As shown in Figure 1, should
Method includes:
Step S110 sends the request of downloading new data to server, receives the data that server returns.
In one embodiment of the invention, include: in the request for the downloading new data which sends
The number of data of downloading is requested, and has been downloaded into the mark of the newest data in database.In this way, server end thinks visitor
The requested data in family end are until the Data Identification that the current newest data of server end includes into the request
Data, and request number of data be the request in the item number for including.Here, what " new " and " old " compared is data
Generation time, " new " is the posterior data of generation time, " old " data first for generation time.
Step S120, whether the data for judging that server returns can be connected with the data with existing in database, if it is holding
Row step S130 executes step S140 if not.
In one embodiment of the invention, when the item number for the data returned in server is less than the number of data of request downloading
It is judged as linking, is judged as when the item number for the data that server returns is greater than or equal to the number of data of request downloading and does not hold in the mouth
It connects.This is because the number of data for the request downloading for including in the request for the downloading new data that server end is sent with client,
With the result of the foundation for being identified as returned data for the newest data having been downloaded into database.
By taking the mark of data is incremented by successively according to the sequencing of its generation time as an example: client has been downloaded into database
In a newest data be identified as 1000,20 data of current request.If received server-side is to the request of client
When, the mark of a newest data for server end to 1050, then server can be returned to client and be identified as 1031~
1050 20 datas, client judge as divergence.If received server-side to client request when, server end
A newest data mark to 1015, then server can be returned to client be identified as 1001~1015 15 numbers
According to client judges as linking.
The data that server returns are saved in database by step S130, and the display of the data of the return is marked
It is set to effectively.Execute step S150.
Step S140, the display label by display existing in database labeled as effective data are all set in vain, so
The data that server returns are saved in database afterwards, and the display label for the data that server returns is set to effectively.It holds
Row step S150.
Step S150 only shows that the display in database is labeled as effective data.
In technical solution shown in FIG. 1, all judge whether are new data and existing data after each request to new data
Linking, then illustrates that data produce tomography when divergence, by being arranged and safeguarding that the display of data marks, and only in display
Show newest continuous data, such user sees that data are continuous data, wherein layer data is not present, thus solves
User cannot know in shown data the problem of with the presence or absence of layer data.
When method shown in FIG. 1 can also be judged as divergence in the step s 120, further by the tomography with divergence
The corresponding tomography section of data is saved in safeguarded tomography section set.Specifically: in the data with server return
The mark of an oldest data and the mark for the newest data having been downloaded into database form an expression tomography section
Array, and by the array be saved in indicate tomography section set array set in.For example, having been downloaded with client above-mentioned
A newest data into database is identified as 1000, and 20 data of current request, received server-side arrives client
When request, the mark of a newest data for server end to 1050, server is identified as 1031 to client return~
For 1050 20 datas, the corresponding tomography section of the layer data of the divergence is that array is [1031,1000].Fault zone
Between two end-point datas 1000 and 1031 of [1031,1000] do not include in layer data, i.e., corresponding layer data is
1001~1030.
To keep technical solution of the present invention clearer, technical solution of the present invention is further described below.
Fig. 2 shows the flow charts of data download method according to an embodiment of the invention.Fig. 3 is shown according to this hair
The data variation schematic diagram of client in the data downloading process of bright one embodiment.Below in conjunction with Fig. 3 to method shown in Fig. 2
It is illustrated, as shown in Fig. 2, the process of new data of client request includes:
Step S202, user end to server send the request of downloading new data.
In one embodiment of the invention, include: in the request for the downloading new data which sends
The number of data of downloading is requested, and has been downloaded into the mark of the newest data in database.
Firstly, client need to determination will the number of data of downloading " request ", be such as under normal circumstances 20.In addition, client
Hold the mark for the newest data for also needing to obtain in data with existing and (have been downloaded into client database), such as Fig. 3
In lines 310.Above-mentioned " number of data of request downloading " and " mark of the newest data in data with existing " are saved as
One variable is spare.Then, client will " number of data of request downloading " and " mark of the newest data in data with existing
Know " it is spliced into a URL, the data for requesting downloading to update to server.
Step S204, client receive the data that server returns.
Herein, server can judge a how many piece should be returned according to " mark of the newest data in data with existing "
Data, and which data returned.Under normal conditions, " mark of the newest data in data with existing " on the server
The form of expression is " request is until the Data Identification " (lines 310 in such as Fig. 3), that is, obtaining the section of the range of data is
" mark of a just infinite newest data into data with existing ", formula are as follows: (∞, the newest data in data with existing
Mark), do not include data specified by the mark of the newest data in the data with existing in range.Meanwhile " request
The number of data of downloading " will also be limited as a kind of condition, i.e., server end " number of data of return " is less than or is equal to
The limitation.Finally, the condition of the returned data of server end are as follows: one, the item number of returned data is less than or is equal to " under request
The number of data of load "；Two, the range for obtaining data is (∞, the mark of the newest data in data with existing), two conditions at
The relationship of "AND".
Whether step S206, the number of data that client judges that server returns are less than or equal to 0, are to then follow the steps
S208, it is no to then follow the steps S210.
Step S208, if the number of data that server returns is less than or equal to 0, then it represents that newest number in client
That the latest data of server end identifies according to mark, i.e. the data of client be it is newest, server end does not update
Data, it is the latest data on server that client, which prompts the user with the latest data in database, no longer need to request, pass
Defeated process terminates.
Step S210, if the number of data that server returns is greater than 0, then it represents that server end has than client most
New data also wants new data, therefore whether the data for continuing to judge that server returns can hold in the mouth with the data with existing in database
It connects, specially judges whether the number of data that server returns is less than the number of data for requesting downloading, be to then follow the steps
S212, it is no to then follow the steps S214.
Step S212, if the number of data that server returns is less than the number of data for requesting downloading, then it represents that service
The data that device returns can be connected with the data of client local, and the data that server returns are saved in database by client
In, and the display label for the data that server this time returns is set to effectively.For example, in one embodiment of the invention, using
The SQL statement of one INSERT, which can be realized, is inserted into the data that server returns in database.Terminate process.
Step S214, if the number of data that server returns is greater than or equal to the number of data for requesting downloading, table
The data for showing that server returns can not be connected with the data of client local, and there are layer datas, then client will break in this
The corresponding tomography section of layer data is saved in safeguarded tomography section set.
In one embodiment of the invention, the oldest data in data that client first returns to server
Identification record gets off, and saves as a variable, in the present embodiment, can be described as " oldest one in server returned data
The mark of data ", as shown in lines 320 in Fig. 3.Then, client is by " mark of the newest data in data with existing ",
As shown in the lines 310 in Fig. 3, a variable is saved as, it is spare.Subsequently, " the Interval Set of tomography is taken out from database
Close " (in such as Fig. 3, there is tomography section at two to be respectively labeled as 331 and 332, then the two are exactly " the Interval Set of tomography altogether
Close ")." tomography section set " is mainly used to record the range intervals of each tomography, and client all has not yet been downloaded in these tomographies
In, but can be requested again to server when client needs.And the purpose for taking out " tomography section set " be will be in the collection
New tomography section is added in conjunction.
In one embodiment of the invention, tomography section is realized using the array list ArrayList in JAVA class libraries
Set.It and is that tomography section is gathered by SQLite sentence and is taken out specific to the way in Android client.Due to taking
Out be Bytes type (also available characters string descriptor tomography section), client can pass through unserializing technology (de-
Serialize) namely the readObject method of the ObjectInputStream class of Android, one is converted by the record
A ArrayList object.And in ArrayList, each single item is all made of the one-dimension array of Integer, and each array has two
A element is respectively intended to indicate two boundaries in the tomography section.Client to do is to by it is previously mentioned " server return
Data in an oldest data mark " and " mark of the newest data in data with existing " as tomography section
Two boundaries, are respectively filled in the one-dimension array of new Integer, are then added in ArrayList object, finally,
Being serialized (serialize) again is a Bytes object namely the ObjectOutputStream of Android
ToByteArray () finally, then is stored back in database.So far, tomography section set is by more new tomographies
Section, 333 in Fig. 3 be the tomography section newly increased.
Step S216, the display label by display existing in database labeled as effective data are all set in vain.
The value of data existing in client (data segment 311 in such as Fig. 3) display label is changed to 0 from 1 (display)
(hiding) will not be shown in the display interface of client with the data with existing section 311 before ensuring tomography 333.Specific practice
Are as follows: by a SQL statement, the value of the display label of all data with existing is changed to 0 (hiding) from 1 (display).
Then data that the data that server returns are saved in database, and server is returned by step S218
Display label is set to effectively.
Client can will be inserted into database by those of server end return data 333 before, and be shown
The value of label is set to 1 (display).So far, entire transmission process terminates.
From the foregoing, it can be seen that, by being arranged and safeguarding display label, only being shown newest continuous in technical solution of the present invention
Data, such user sees that data are continuous data, is furthermore also recorded between fault zone, in this way when user wants to request tomography
It, can be according to the corresponding layer data of tomography interval requests of record when data.
