org.apache.bcel.generic.Type

- Packages that use Type
  Package | Description
  --- | ---
  org.apache.bcel.classfile | This package contains the classes that describe the structure of a Java class file and a class file parser.
  org.apache.bcel.generic | This package contains the "generic" part of the Byte Code Engineering Library, i.e., classes to dynamically modify class objects and byte code instructions.
