org.eclipse.jdt.core.dom.Type

Abstract base class of all type reference AST node types. A type node represents a reference to a primitive type (including void), to an array type, or to a simple named type (or type variable), to a qualified type, to a parameterized type, to a union type, to an intersection type, or to a wildcard type. Note that not all of these are meaningful in all contexts; for example, a wildcard type is only meaningful in the type argument position of a parameterized type. UnionType got introduced in JLS4 to support common catch blocks for disjunctive types. For JLS8, optional annotations indicated by {Annotation} got added.
