public class TypeDeclaration
extends AbstractTypeDeclaration

Type declaration AST node type. A type declaration is the union of a class declaration and an interface declaration. For JLS2:

 TypeDeclaration:
 		ClassDeclaration
 		InterfaceDeclaration
 ClassDeclaration:
      [ Javadoc ] { Modifier } class Identifier
			[ extends Type]
			[ implements Type { , Type } ]
			{ { ClassBodyDeclaration | ; } }
 InterfaceDeclaration:
      [ Javadoc ] { Modifier } interface Identifier
			[ extends Type { , Type } ]
 			{ { InterfaceBodyDeclaration | ; } }
 
For JLS3, type parameters and reified modifiers (and annotations) were added, and the superclass type name and superinterface types names are generalized to type so that parameterized types can be referenced:
 TypeDeclaration:
 		ClassDeclaration
 		InterfaceDeclaration
 ClassDeclaration:
      [ Javadoc ] { ExtendedModifier } class Identifier
			[ < TypeParameter { , TypeParameter } > ]
			[ extends Type ]
			[ implements Type { , Type } ]
			{ { ClassBodyDeclaration | ; } }
 InterfaceDeclaration:
      [ Javadoc ] { ExtendedModifier } interface Identifier
			[ < TypeParameter { , TypeParameter } > ]
			[ extends Type { , Type } ]
 			{ { InterfaceBodyDeclaration | ; } }
 

When a Javadoc comment is present, the source range begins with the first character of the "/**" comment delimiter. When there is no Javadoc comment, the source range begins with the first character of the first modifier or annotation (if any), or the first character of the "class" or "interface" keyword (if no modifiers or annotations). The source range extends through the last character of the "}" token following the body declarations.

2.0

Deprecated. In the JLS3 API, this method is replaced by getSuperclassType(), which returns a Type instead of a Name.

Returns the name of the superclass declared in this type declaration, or null if there is none (JLS2 API only).

Note that this child is not relevant for interface declarations (although it does still figure in subtree equality comparisons).

Throws:
UnsupportedOperationException - if this operation is used in a JLS2 AST
Since:
3.1

setSuperclass
