The org.netbeans.modules.classfile package supports direct access to a Java Virtual Machine classfile contents.
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.
Java 11 added a new constant pool entry type to support the constantDynamic instruction.
Introduced ModulePackages, ModuleMainClass, ModuleTarget attributes according to recent JDK 9 JLS
Updated ClassFile to recent JDK 9 JLS.
Added isModule method into a ClassFile to test that a classfile represents a module descriptor.
Java 9 added a Module attribute for module-info.class describing the module.
The normal usecase is for a client wanting to inspect a classfile. A
instance is created with either a
InputStream instance. All attributes of the classfile are available as properties,
