org::netbeans::lib::profiler::classfile::ClassFileCache Class Reference

List of all members.

Detailed Description

Fixed-size cache of binary classes (.class files). Used to avoid flooding memory with class files when performing intensive method scanning, that may touch thousands of classes. Currently uses LRU eviction policy. A separate, currently no-eviction cache, is maintained for classes supplied by the VM.
