Overview (Classfile Reader)

Classfile Reader
Package	Description
org.netbeans.modules.classfile	The org.netbeans.modules.classfile package supports direct access to a Java Virtual Machine classfile contents.

classfile The ClassFile library is an API to read Java classfiles, as described by The Java Virtual Machine Specification. Given a file or stream reference to a Java classfile, the API provides read-only access to all of its class attributes, including type information, methods and fields, generics support (if any), etc.
NOTE: this library is not really a NetBeans module, in that it doesn't have any NetBeans references. It therefore has nothing pluggable, no NetBeans Lookups, and is not extensible.
