Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the embodiments of the present invention are explained in detail.Yet, persons of ordinary skill in the art may appreciate that in each execution mode of the present invention, in order to make the reader understand the application better, many ins and outs have been proposed.But, even without these ins and outs with based on many variations and the modification of following each execution mode, also can realize each claim of the application technical scheme required for protection.
The first execution mode of the present invention relates to a kind of read/writing control method of mobile phone file.In the present embodiment, the read-write of mobile phone file realizes by an intelligent file read-write interface.The below is specifically described Fig. 1, reading and writing operating process shown in Figure 2 respectively.
Fig. 1 be in the time of need carrying out read operation in present embodiment (as open, revise, delete, append to write etc. need the read operation carried out) flow chart.In step 101, call the intelligent file read-write interface.
Then, in step 102, this intelligent file read-write interface finds corresponding path prefix according to the memory location of the first-selection of Set For Current.
Specifically, for each memory location in mobile phone arranges corresponding path prefix, the memory location is corresponding one by one with path prefix in advance.Such as have 3 memory locations in mobile phone: system file memory block, fuselage memory block, external connection of storage card have 3 path prefix corresponding with these 3 memory locations respectively.As the corresponding fuselage of path prefix A correspondence system file storage area, path prefix B memory block, the corresponding external connection of storage card of path prefix C.And which memory location the file in mobile phone preferentially is stored in and can arranges, and the memory location of set preferential storage is first-selected memory location.In this step, this intelligent file read-write interface can find corresponding path prefix (being path prefix B) according to the memory location (as the fuselage memory block) of the first-selection of Set For Current.
Then, in step 103, generate the complete file path.Specifically, this intelligent file read-write interface is with the path prefix that finds and the file path composition complete file path of receiving.Wherein, the file path that the file path of receiving namely imports into from this intelligent file read-write interface can be that the programmer is imported into to this intelligent file read-write interface, can be also that other modules in mobile phone are imported into to this intelligent file read-write interface.Such as, the corresponding path prefix that finds is path prefix B, the file path that the programmer is imported into to this intelligent file read-write interface is certain concrete Folder Name " music file ", so, this intelligent file read-write interface is with " path prefix B " and " music file " composition complete file path.
Then, in step 104, this intelligent file read-write interface inspection is under this complete file path, whether corresponding file to be arranged.If corresponding file is arranged, enter step 105, if there is no corresponding file, enter step 107.
In step 105, this intelligent file read-write interface uses this document, namely the file that finds according to this complete file path is carried out read operation.
Then, in step 106, this intelligent file read-write interface returns and calls result.
If in step 104, the judgement complete file does not have corresponding file under the path, enters step 107.In step 107, this intelligent file read-write interface judges whether that all path prefix all attempted.
Specifically, in the present embodiment, consider that the user might change the memory location of first-selection, and the content of read-write is still in the memory location that is kept at before changing before, in this case, this intelligent file read-write interface will can not find corresponding file under the complete file path that is comprised of after changing path prefix and file path.Therefore, other path prefix and the file path of receiving need to be made up, until under the complete file path that obtains after combination, corresponding file is arranged.Because other path prefix must comprise the corresponding path prefix in memory location before changing, therefore, under normal circumstances, by successively other path prefix and the file path received being made up, can find corresponding file under the complete file path that obtains after combination.If all path prefix were all attempted, do not find yet corresponding file, abnormal conditions have occured in explanation, enter step 109, and this intelligent file read-write interface malloc failure malloc also returns to failure result.If also there is the path prefix of not attempting, enter step 108, the complete file path of using next path prefix and file path to form.
In the present embodiment, can for each path prefix, priority orders be set in advance.Other path prefix and the file path of receiving are being made up, until have in the step of corresponding file under the complete file path that obtains after combination, carry out described combination according to the priority orders of other path prefix, the path prefix that other path prefix medium priorities are higher is preferentially carried out described combination.
Such as for above-mentioned case, the priority of path prefix A is greater than path prefix B, and the priority of path prefix B is greater than path prefix C.The corresponding path prefix in memory location after changing is path prefix A, that is to say, under path prefix A and the file path that imports into from this intelligent file read-write interface form complete file path, when can not find corresponding file, other path prefix are path prefix B and path prefix C.And due to the priority of path prefix B greater than path prefix C, therefore, when other path prefix are made up with the file path of receiving, preferentially with path prefix B and the file path composition complete file path of importing into from this intelligent file read-write interface, under path prefix B and the file path that imports into from this intelligent file read-write interface form the complete file path, when still can not find corresponding file, reattempt and use with path prefix C and the file path composition complete file path of importing into from this intelligent file read-write interface, until searched all memory locations.
Fig. 2 is the flow chart of (as a newly-built document) in the time of need carrying out write operation in present embodiment.In step 201, call the intelligent file read-write interface.
Then, in step 202, this intelligent file read-write interface finds corresponding path prefix according to the memory location of the first-selection of Set For Current.This step is identical with step 102, does not repeat them here.
Then, in step 203, this intelligent file read-write interface generates the complete file path, and this step is identical with step 103, does not repeat them here.
Then, in step 204, this intelligent file read-write interface carries out write operation according to the complete file path of this generation.Content is written to known indicated position, complete file path, belongs to the common practise of this area, do not repeat them here.
Then, in step 205, this intelligent file read-write interface returns and calls result.
In the present embodiment, set in advance the preferential memory location of a unification due to the user, therefore, when carrying out the reading and writing operation, only need programmer's input or obtain concrete file path (as concrete Folder Name) by calling other modules, can be by the path prefix (being root) that will find in conjunction with one of this concrete file path (being subdirectory) composition complete file path, thus carry out read operation or write operation.And need not to eject the selection dialog box as traditional way, perhaps read respectively the user each is used the preferential memory location that arranges.For the developer, also need not to select current the needs with which memory location (because first-selected memory location presets) when coding.Thereby can make the user can use more easily the relevant application of various file accesses, the developer can complete the associative operation of file more easily, and the storage of saving most of module arranges development.
And, when there is no corresponding file under the complete file path that forms behind the memory location in change, other path prefix (path prefix that namely before changing memory location may be corresponding) are made up with the file path of receiving, until under the complete file path that obtains after combination, corresponding file is arranged.Not only can unify to revise the memory location, and the file path that makes the developer can make at an easy rate the application of developing can adapt to the user arranges change, and be kept at before changing the file in another memory block, still can normally access after changing.
The second execution mode of the present invention relates to a kind of read/writing control method of mobile phone file.The second execution mode improves on the basis of the first execution mode, main improvements are: in second embodiment of the invention, when mobile phone carries out the relevant read operation of specific program or write operation at needs, according to the default path of this specific program, carry out read operation or write operation.
That is to say, in the present embodiment, except the intelligent file read-write interface, also provide one group of traditional file read-write interface, for the module that does not need to change read and write position with use, as system kernel etc.
Due to for system file, its read and write position should be fixed, and therefore by compartment system file and ordinary file, specific program (as operating relevant program to system) is set default path, can promptly find read and write position, thereby effectively improve the mobile phone operating rate.
