Packages that use java.lang.invoke
Package
Description
java.lang
Provides classes that are fundamental to the design of the Java programming language.
java.lang.classfile
Provides classfile parsing, generation, and transformation library.
java.lang.constant
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.
java.lang.foreign
Provides low-level access to memory and functions outside the Java runtime.
java.lang.invoke
The `java.lang.invoke` package provides low-level primitives for interacting with the Java Virtual Machine.
java.lang.runtime
The `java.lang.runtime` package provides low-level runtime support for the Java language.
jdk.dynalink
Contains interfaces and classes that are used to link an `invokedynamic` call site.
jdk.dynalink.beans
Contains the linker for ordinary Java objects.
jdk.dynalink.linker
Contains interfaces and classes needed by language runtimes to implement their own language-specific object models and type conversions.
jdk.dynalink.linker.support
Contains classes that make it more convenient for language runtimes to implement their own language-specific object models and type conversions by providing basic implementations of some classes as well as various utilities.
jdk.dynalink.support
Contains classes that make using Dynalink more convenient by providing basic implementations of some classes as well as various utilities.

  A `CallSite` is a holder for a variable `MethodHandle`, which is called its `target`.
  MethodHandle
  A method handle is a typed, directly executable reference to an underlying method, constructor, field, or similar low-level operation, with optional transformations of arguments or return values.
  MethodHandles.Lookup
