Title: Device and method for footprint reduction of preloaded class
Inventor: KAWAHARA HIDEYA
IPC: G06F9/44
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To reduce the ROM space needed for preloaded Java classes by generating an access function and a member declaration so that a stored value and one set of value indexes obtained by determining the type of a data structure so as to define preloaded classes are usable as selected members in in-execution environment. SOLUTION: The type of the data structure includes >=1 members and the type of the data structure represented by >=1 class files 130 is determined so as to define plural preloaded classes 148. Individual values that members possibly have are determined and stored for a subset of members selected so as to reduce the size of a corresponding internal data structure constituting a preloaded class 148. One set of value indexes for addressing the stored values is generated and the access function and member declaration are so generated that the in-execution environment can use selected members represented as the stored values and one set of value indexes.
