Uses of Package java.lang.invoke (Java SE 12 & JDK 12 )

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.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.invoke	The `java.lang.invoke` package provides low-level primitives for interacting with the Java Virtual Machine.
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.

Classes in java.lang.invoke used by java.lang
Class	Description
MethodHandles.Lookup	A lookup object is a factory for creating method handles, when the creation requires access checking.
MethodType	A method type represents the arguments and return type accepted and returned by a method handle, or the arguments and return type passed and expected by a method handle caller.
TypeDescriptor	An entity that has a field or method type descriptor
TypeDescriptor.OfField	An entity that has a field type descriptor

Class	Description
CallSite	A `CallSite` is a holder for a variable `MethodHandle`, which is called its `target`.
LambdaConversionException	LambdaConversionException
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.
MethodHandleInfo	A symbolic reference obtained by cracking a direct method handle into its consitutent symbolic parts.
MethodHandles.Lookup	A lookup object is a factory for creating method handles, when the creation requires access checking.
MethodType	A method type represents the arguments and return type accepted and returned by a method handle, or the arguments and return type passed and expected by a method handle caller.
MutableCallSite	A `MutableCallSite` is a `CallSite` whose target variable behaves like an ordinary field.
StringConcatException	StringConcatException is thrown by `StringConcatFactory` when linkage invariants are violated.
SwitchPoint	A `SwitchPoint` is an object which can publish state transitions to other threads.
TypeDescriptor	An entity that has a field or method type descriptor
TypeDescriptor.OfField	An entity that has a field type descriptor
TypeDescriptor.OfMethod	An entity that has a method type descriptor
VarHandle	A VarHandle is a dynamically strongly typed reference to a variable, or to a parametrically-defined family of variables, including static fields, non-static fields, array elements, or components of an off-heap data structure.
VarHandle.AccessMode	The set of access modes that specify how a variable, referenced by a VarHandle, is accessed.
VarHandle.VarHandleDesc	A nominal descriptor for a `VarHandle` constant.
