Packages that use InstructionHandle

Package	Description
org.apache.bcel.generic	Generic part of the Apache Byte Code Engineering Library (BCEL), classes to dynamically modify class objects and byte code instructions.
org.apache.bcel.util	Utility classes for the Apache Byte Code Engineering Library (BCEL), namely: Collection classes for JavaClass objects A converter for class files to HTML A tool to find instructions patterns via regular expressions A class to find classes as defined in the CLASSPATH A class loader that allows to create classes at run time
