METHOD AND DEVICE FOR PREPROCESSING AND PACKAGING OF CLASS FILE

摘要

PROBLEM TO BE SOLVED: To obtain a method and device for preprocessing and packaging a class file by obtaining a reduced class file by removing copied elements from plural class files and constituting a plural-class file including the reduced class file and a common table. SOLUTION: A server 100 includes Java development environment 104. A preprocessor checks respective class files in one set of class files 107 to search for copied information in the form of a redundancy contact included in a constant loop. The copied information is arranged in an individual common table, and all the occurrences of constants are removed from the constant loops of individual class files. In preprocessing, memory allocation matters are decided for the respective class files and used to determine the allocation matters of the whole set of class files. The memory allocation matters and reduced class file are packaged into a single unit in the multi-class file.
