GenericDeclaration

public interface GenericDeclaration
implements AnnotatedElement

java.lang.reflect.GenericDeclaration

Known indirect subclasses

Class<T>, Constructor<T>, Executable, Method

Class<T>	Instances of the class `Class` represent classes and interfaces in a running Java application.
Constructor<T>	`Constructor` provides information about, and access to, a single constructor for a class.
Executable	A shared superclass for the common functionality of `Method` and `Constructor`.
Method	A `Method` provides information about, and access to, a single method on a class or interface.

A common interface for all entities that declare type variables.

Summary

Public methods
`abstract TypeVariable[]<?>`	`getTypeParameters()` Returns an array of `TypeVariable` objects that represent the type variables declared by the generic declaration represented by this `GenericDeclaration` object, in declaration order.

Inherited methods

From interface java.lang.reflect.AnnotatedElement

`abstract <T extends Annotation> T`	`getAnnotation(Class<T> annotationClass)` Returns this element's annotation for the specified type if such an annotation is present, else null.
`abstract Annotation[]`	`getAnnotations()` Returns annotations that are present on this element.
`default <T extends Annotation> T[]`	`getAnnotationsByType(Class<T> annotationClass)` Returns annotations that are associated with this element.
`default <T extends Annotation> T`	`getDeclaredAnnotation(Class<T> annotationClass)` Returns this element's annotation for the specified type if such an annotation is directly present, else null.
`abstract Annotation[]`	`getDeclaredAnnotations()` Returns annotations that are directly present on this element.
`default <T extends Annotation> T[]`	`getDeclaredAnnotationsByType(Class<T> annotationClass)` Returns this element's annotation(s) for the specified type if such annotations are either directly present or indirectly present.
`default boolean`	`isAnnotationPresent(Class<? extends Annotation> annotationClass)` Returns true if an annotation for the specified type is present on this element, else false.

Public methods

getTypeParameters

Added in API level 1

 public abstract TypeVariable[]<?> getTypeParameters ()

Returns an array of TypeVariable objects that represent the type variables declared by the generic declaration represented by this GenericDeclaration object, in declaration order. Returns an array of length 0 if the underlying generic declaration declares no type variables.

Returns
`TypeVariable[]<?>`	an array of `TypeVariable` objects that represent the type variables declared by this generic declaration

Throws
`GenericSignatureFormatError`	if the generic signature of this generic declaration does not conform to the format specified in The Java™ Virtual Machine Specification
