Interface MethodDescription

All Superinterfaces:

AnnotatedElement, ByteCodeElement, ByteCodeMethod, DeclaredInType, ModifierReviewable

All Known Implementing Classes:

InstrumentedType.AbstractBase.MethodToken, MethodDescription.AbstractMethodDescription, MethodDescription.ForLoadedConstructor, MethodDescription.ForLoadedMethod, MethodDescription.Latent

public interface MethodDescription
extends ModifierReviewable, ByteCodeMethod, DeclaredInType, AnnotatedElement

Implementations of this interface describe a Java method, i.e. a method or a constructor. Implementations of this interface must provide meaningful equal(Object) and hashCode() implementations.

Modifier and Type	Interface and Description
static class	MethodDescription.AbstractMethodDescription An abstract base implementation of a method description.
static class	MethodDescription.ForLoadedConstructor An implementation of a method description for a loaded constructor.
static class	MethodDescription.ForLoadedMethod An implementation of a method description for a loaded method.
static class	MethodDescription.Latent A latent method description describes a method that is not attached to a declaring TypeDescription but stands for itself.
