Classfile Reader

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

Classfile Reader
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.

What is New (see all changes)?

Dec 6 '05 Support for Java 6 classfile enhancements.
Java 6 added a new classfile verifier, which uses the new code attribute, StackMapTable. This adds support for that attribute.
Nov 9 '04 Support for Java 5 classfile enhancements.
Java 5 added several attributes to the JVM classfile format to support generics, annotations, varargs, and enums. The classfile module was enhanced to add access to all of these new attributes.

Use Cases

The normal usecase is for a client wanting to inspect a classfile. A ClassFile instance is created with either a String path, File or InputStream instance. All attributes of the classfile are available as properties, such as getSourceFileName or getMethods.
