Packages that use ClassDesc
Package
Description
Provides classes that are fundamental to the design of the Java
programming language.
Provides classfile parsing, generation, and transformation library.
Provides interfaces describing
class file attributes for the java.lang.classfile library.Provides interfaces describing constant pool entries for the
java.lang.classfile library.Provides interfaces describing code instructions for the
java.lang.classfile library.Classes and interfaces to represent nominal descriptors for run-time
entities such as classes or method handles, and classfile entities such as
constant pool entries or
invokedynamic call sites.The
java.lang.invoke package provides low-level primitives for interacting
with the Java Virtual Machine.-
