[embodiment]
Fig. 1 shows the flow process of the storage means of resource file among the embodiment, and detailed process is as follows:
In step S100, obtain the resource file catalogue, generate the resource file mapping table according to described resource file catalogue.In one embodiment, the resource file mapping table has write down resource file catalogue, the side-play amount of resource file data in the resource packaging file and the size of resource file data.
In step S102,, set up the header structure and the index area of resource packaging file according to the resource file mapping table.In one embodiment, the form of resource packaging file comprises header structure, three parts in index area and data field as shown in Figure 2, and the resource packaging file is a kind of read-only file.Header structure has write down quantity, the side-play amount of index area and the size of index area that flows in the realization sign, resource file of resource packaging file.The realization sign of resource packaging file is used to identify the form of packaging file, and the quantity that flows in the resource file has write down the quantity of the resource file of being packed in the resource bundle.The index area has write down resource file data catalogue, the side-play amount of resource file data in the resource packaging file and the size of resource file data.
In step S104,, resource file data is packed in the resource packaging file according to resource file mapping table traversal resource file.
In one embodiment, after resource file data packed, upgrade the content of index area.Particularly, be the side-play amount of resource file data in the resource packaging file according to packing, upgrade the index area content.
Said method has been set up the resource packaging file, this resource packaging file comprises header structure, index area and data field, the resource file data packing is stored in the data field of resource packaging file, then can be with a plurality of indivisible in logic resource file that needs in the IM software, promptly context has specific logic implication and is to be mutually related a plurality of available data files (as image in the IM software program, the Voice ﹠ Video file), be packaged into an organic whole, do not need resource file is carried out any change, thereby avoided the imperfect interface confusion of bringing of resource file, the greatly convenient management of software to read-only resource file.
Fig. 3 shows the flow process of the access method of resource file among the embodiment, and detailed process is as follows:
In step S200, open the resource packaging file, resolve the header structure of described resource packaging file.
In step S202,, resolve the index area of described resource packaging file according to described header structure.Owing to write down the index area side-play amount in the header structure, can obtain content in the index area according to header structure, the content in the index area comprises the side-play amount of resource file data, this side-play amount has promptly shown the memory location of resource file data in the data field, packing back.
In step S204,, read the resource file data in the described resource packaging file according to the content in the described index area.
Because the resource file in the IM software is packed in the resource packaging file, during visit, header structure and index area by the resolving resource packaging file, and read resource file data in the resource packaging file according to the content in the index area, thereby realized the fast access of resource file, the software that has promoted the user is experienced.
The memory access device of resource file comprises storer 100 and the packaging file of storer 100 is carried out the addressed location 200 of data access.Fig. 4 shows the storer 100 of a resource file, wherein:
