Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038]The core idea of ​​the method of the present invention is: preset a string management unit for storing the hash value of a string; when an external functional unit needs to quote a string, send a string reference application carrying a corresponding string to the string management unit; After receiving the string reference application, the string management unit calculates the hash value of the string carried in the application, and then searches for the calculated hash value from the hash Find the character string carried in the application in the character string corresponding to the calculated hash value, and output the reference information of the character string; the external functional unit references the character string according to the output refere...

Abstract

The disclosed reference method for character string comprises: pre-setting the string management unit to store the hex value of string; when referring to the string, sending reference request with opposite string to the management unit; calculating the carried hex value, finding out the result from self stored values, and finding out the opposite string for output; finally, referring the string by external function unit. This invention optimizes string storage, and saves system memory and CPU occupancy.

Description

technical field [0001] The present invention relates to the field of computer application technology, in particular to a string reference method. Background technique [0002] In C language and C++ language, strings are used as indexes of other objects or objects themselves. Traditional strings are generated and stored independently by functional units that refer to strings according to their own needs, and then used. When string comparison is required during the process, it is necessary to compare all the characters of the strings to be compared one by one to determine whether the strings to be compared are the same. string delete. [0003] On the one hand, this traditional character string reference method requires each functional unit to save the character string independently, so it may cause the same character string to be stored in multiple functional units and redundantly occupy the system storage space. On the other hand, since the length of the character string us...
