Class file archives with reduced data volume

摘要

A method for packaging program resources includes collecting a set of the program resources that comprises a plurality of object files, which contain data structures having entries that are constants and methods that reference the entries. The data structures in at least some of the object files are combined into a common data pool, in which semantically-identical entries in different ones of the files are represented by a single consolidated entry, irrespective of whether the entries in the different files are syntactically identical. The set of the program resources is packaged together with the common data pool in a combined output file.
