Uses of Interface
java.lang.constant.ClassDesc
Packages that use ClassDesc
Package
Description
Provides classes that are fundamental to the design of the Java
programming language.
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.-
