Examples of com.sun.mirror.declaration.TypeDeclaration

com.sun.mirror.declaration.TypeDeclaration
Represents the declaration of a class or interface. Provides access to information about the type and its members. Note that an {@linkplain EnumDeclaration enum} is a kind of class,and an {@linkplain AnnotationTypeDeclaration annotation type} isa kind of interface.
While a TypeDeclaration represents the declaration of a class or interface, a {@link DeclaredType} represents a classor interface type, the latter being a use (or invocation) of the former. The distinction is most apparent with generic types, for which a single declaration can define a whole family of types. For example, the declaration of {@code java.util.Set} corresponds to the parameterized types{@code java.util.Set} and {@code java.util.Set}(and many others), and to the raw type {@code java.util.Set}.
{@link com.sun.mirror.util.DeclarationFilter}provides a simple way to select just the items of interest when a method returns a collection of declarations. @author Joseph D. Darcy @author Scott Seligman @version 1.5 05/11/17 @see DeclaredType @since 1.5
