Uses of Class
org.apache.bcel.generic.ConstantPoolGen
Packages that use ConstantPoolGen
Package
Description
Generic part of the Apache Byte Code Engineering Library (BCEL), classes to dynamically modify class objects
and byte code instructions.
A PassVerifier class mostly used internally by JustIce, yielding a control flow graph for public use as a nice side effect.
