Embodiment
For making technical characterictic of the present invention and the effect reached there are further understanding and understanding, cooperate detailed explanation, explain as follows in order to preferred embodiment and accompanying drawing:
Preferably, a kind of method that realizes software version compatibility of the present invention,
Step 1: store first structure, said first structure defines the size of said first structure and the type of said first structure; The type of said first structure comprises the size information of one or more second information structure, and each said second information structure defines the size of said second information structure and the specifying information of said second information structure;
Step 2: read first structure, obtain the size information of one second information structure; Whether the size of the information structure that the size of comparison second information structure is corresponding with current version equates;
Step 3: when both are equal, read the specifying information of said second information structure, read the size information of next second information structure again, and judge whether said next second information structure is last, if then finish; , then do not return step 2;
When said second information structure during, read the specifying information of the corresponding information structure of current version greater than the corresponding information structure of current version big or small; Read the size information of next second information structure again, and judge whether said next second information structure is last, if then finish; , then do not return step 2;
When said second information structure during, the information structure that the initialization current version is corresponding, read the specifying information of said second information structure again less than the corresponding information structure of current version big or small; Read the size information of next second information structure then, and judge whether said next second information structure is last, if then finish; , then do not return step 2.
Preferably, in the step 1, first structure definition is used for describing each information structure, and first structure defined the size of first structure and the type of said first structure, and fixing first attribute field of first structure is its size; And the type of first structure comprises the size information of one or more second information structure, shown in the following structure,
Struct is a structure, and tagSizeInfo is the first structure type name, and int nSelfSize then is the size information of first structure, is himself size, A; B; C; D is the member of first structure, the second corresponding dissimilar respectively information structure size information; Int nStructASize is the size information of A information structure, and int nStructBSize is the size information of B information structure ...; Such as one first structure of definition; This first structure is the brand and the different brands automobile descriptor size of all automobiles of record * * city; Then int nSelfSize is the size of first structure self, and int nStructASize then can be regarded as the descriptor size of the automobile of A brand; Int nStructB then can be regarded as the descriptor size of the automobile of B brand, and int nStructCSize then can be regarded as the descriptor size of the automobile of C brand ....In addition, preferred, each said second information structure defines the size of said second information structure and the specifying information of said second information structure, shown in the following structure, is the information structure of A;
Be directed to second information structure, int nStructASize is the size of A information structure, is himself size; More specifically; Like the A brand is Cherry, and in the last information structure that shows, int nSelfSize is for describing the size of Cherry's automobile information structure; Be that it is self size; Int nAttrA, int nAttrB, int nAttrC describe the specifying information of Cherry's automobile information structure, describe the engine performance of Cherry's automobile like int nAttrA, and int nAttrB describes Cherry's vehicle glass performance or the like; It has described the specifying information of each information structure.
Preferably, when execution in step 2, read first structure, obtain the size information of one second information structure; Whether the size of the information structure that the size of comparison second information structure is corresponding with current version equates; Because first information structure has generally all comprised the size information of a plurality of second information structures, and the size of each second information structure is all different, and defined specifying information also possibly distinguished to some extent; Therefore relatively the time, the size of the information structure that at first relatively second information structure of deposit is corresponding with current version has three kinds of situation this moment; Be step 3, relatively judge link.
Preferably, step 3 when both are equal, reads the specifying information of said second information structure, reads the size information of next second information structure again, and judges whether said next second information structure is last, if then finish; , then do not return step 2; In this step, compare both sizes, promptly compare the size of intnSelfSize; When equating, directly read the specifying information of back, such as, more all be to describe Cherry's automobile, and equal and opposite in direction, then read specifying information wherein, like the engine performance of Cherry's automobile, Cherry's vehicle glass performance or the like.
Therefore and because second information structure has a plurality ofly, before opening software, need all second information structure information are once compared; Be equivalent to initialized process, therefore, will continue more next second information structure at relatively intacter first second information structure; Simultaneously will judge also whether all second information structures read and finish, if; Then end operation is opened software; If not, then continue to return step 2 and compare again, up to relatively intacter last second information structure, complete operation.
When both are unequal, situation about promptly being greater than or less than, same, when said second information structure during, read the specifying information of the corresponding information structure of current version greater than the corresponding information structure of current version big or small; Read the size information of next second information structure again, and judge whether said next second information structure is last, if then finish; , then do not return step 2.
When said second information structure during, the information structure that the initialization current version is corresponding, read the specifying information of said second information structure again less than the corresponding information structure of current version big or small; Read the size information of next second information structure then, and judge whether said next second information structure is last, if then finish; , then do not return step 2.
Preferably, aforesaid way can pass through example description, as original; The software version of user's deposit is 2003 editions a office software, and the version of the current use of user in later stage is 2007 editions a office software, because both versions are different; When therefore using, multiple newly-increased function need not to use; Therefore original, the software version of user's deposit is equivalent to the storing process in the step 1; And the user in later stage when the software that uses redaction is opened, is equivalent to the comparison and the deterministic process of step 2 and step 3 in the process flow diagram; Through second information structure in first structure is compared, when both equal and opposite in directions, the version that uses before and after explaining is identical; And in the present embodiment, because prototype version is lower than current version, be equivalent in the step 3; When said second information structure during less than the corresponding information structure of current version big or small; Therefore, the information structure that the initialization current version is corresponding, this process is equivalent to use second information structure of new function to carry out initialization with need not; Initialization agreement default value 0 is in state for this function; Again through reading the specifying information of said second information structure, promptly be equivalent to read the specifying information of second information structure of deposit, use the function that needs in the version of deposit; Promptly only need to open 2003 editions office softwares the function that will open, and 2007 editions office software functions more newly-increased than 2003 editions office softwares will be initialised.In this process; Second information structure for what's new; The agreement default value is 0 for this function is in disabled status, and when second information structure of deposit during less than the corresponding information structure of current version big or small, the part assignment that the information structure that current version is corresponding surpasses second information structure of depositing is 0; Perhaps that current version is the corresponding equal assignment of information structure be 0 all can, promptly be defaulted as and do not start functional status; And when deposit second information structure during greater than the corresponding information structure of current version big or small; Then only read the part that needs; To increase second information structure of corresponding increase function in first structure newly, but this part will can not reflect in first structure of deposit.
The method of realization software version compatibility provided by the invention can be opened the configure packet of any one version in the software life-cycle; And can guarantee all functions of operational system software release phase of living in accurately; It still is the product operation maintenance stage no matter for product development stage; The change of internal data structure can both guarantee that original configuration comes into force, and has greatly improved efficient, and speed is fast.
