# Uses of Interface
java.lang.invoke.TypeDescriptor

Packages that use TypeDescriptor
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.
java.lang.runtime
The `java.lang.runtime` package provides low-level runtime support for the Java language.

  Modifier and Type
  Interface
  Description
  `static interface`
  `TypeDescriptor.OfField<F extends TypeDescriptor.OfField<F>>`
  An entity that has a field type descriptor.
  `static interface`
  `TypeDescriptor.OfMethod<F extends TypeDescriptor.OfField<F>,M extends TypeDescriptor.OfMethod<F,M>>`
  An entity that has a method type descriptor Method descriptors conforming to JVMS 4.3.3 can be described nominally via `MethodType::describeConstable`; otherwise they cannot be described nominally.

  Description
  `final class`
  `MethodType`

  Method
  Description
  `static Object`
  ObjectMethods.`bootstrap(MethodHandles.Lookup lookup, String methodName, TypeDescriptor type, Class<?> recordClass, String names, MethodHandle... getters)`
  Bootstrap method to generate the `Object.equals(Object)`, `Object.hashCode()`, and `Object.toString()` methods, based on a description of the component names and accessor methods, for either `invokedynamic` call sites or dynamic constant pool entries.
