DeclaredType

public interface DeclaredType implements ReferenceType
Represents a declared type, either a class type or an interface type. This includes parameterized types such as {@code java.util.Set} as well as raw types.

While a TypeDeclaration represents the declaration of a class or interface, a DeclaredType represents a class or interface type, the latter being a use of the former. See {@link TypeDeclaration} for more on this distinction.

A DeclaredType may represent a type for which details (declaration, supertypes, etc.) are unknown. This may be the result of a processing error, such as a missing class file, and is indicated by {@link #getDeclaration()} returning null. Other method invocations on such an unknown type will not, in general, return meaningful results.

Fields Summary
Constructors Summary
Methods Summary
public java.util.CollectiongetActualTypeArguments()
Returns (in order) the actual type arguments of this type. For a generic type nested within another generic type (such as {@code Outer.Inner}), only the type arguments of the innermost type are included.

return
the actual type arguments of this type, or an empty collection if there are none

public com.sun.mirror.type.DeclaredTypegetContainingType()
Returns the type that contains this type as a member. Returns null if this is a top-level type.

For example, the containing type of {@code O.I} is the type {@code O}, and the containing type of {@code O.I} is the type {@code O}.

return
the type that contains this type, or null if this is a top-level type

public com.sun.mirror.declaration.TypeDeclarationgetDeclaration()
Returns the declaration of this type.

Returns null if this type's declaration is unknown. This may be the result of a processing error, such as a missing class file.

return
the declaration of this type, or null if unknown

public java.util.CollectiongetSuperinterfaces()
Returns the interface types that are direct supertypes of this type. These are the interface types implemented or extended by this type's declaration, with any type arguments substituted in.

For example, the interface type extended by {@code java.util.Set} is {@code java.util.Collection}.

return
the interface types that are direct supertypes of this type, or an empty collection if there are none
