Interface Type

All Superinterfaces:
Mirror
All Known Subinterfaces:
ArrayType, BooleanType, ByteType, CharType, ClassType, DoubleType, FloatType, IntegerType, InterfaceType, LongType, PrimitiveType, ReferenceType, ShortType, VoidType

public interface Type
extends Mirror
The mirror for a type in the target VM. This interface is the root of a type hierarchy encompassing primitive types and reference types.

A Type may be used to represent a run-time type:

Value.type()
or a compile-time type:
Field.type()
Method.returnType()
Method.argumentTypes()
LocalVariable.type()
ArrayType.componentType()

The following tables illustrate which subinterfaces of Type are used to mirror types in the target VM --

Subinterfaces of PrimitiveType
Type declared in target as Is mirrored as an instance of
boolean BooleanType
byte ByteType
char CharType
double DoubleType
float FloatType
int IntegerType
long LongType
short ShortType
void VoidType
Subinterfaces of ReferenceType
Type declared in target as For example Is mirrored as an instance of
a class Date ClassType
an interface Runnable InterfaceType
an array (any) ArrayType
int[] ArrayType whose componentType() is IntegerType
Date[] ArrayType whose componentType() is ClassType
Runnable[] ArrayType whose componentType() is InterfaceType

  • Method Details

    • signature

      String signature()
      Returns the type signature for this type. The result is of the same form as the string returned by Class.descriptorString(). The returned string is a type descriptor conforming to JVMS 4.3.2 if this type can be described nominally. Otherwise, the returned string is not a type descriptor.
      Returns:
      the type signature
    • name

      String name()
      Returns the name of this type. The result is of the same form as the name returned by Class.getName(). The returned name may not be a binary name.
      Returns:
      the name of this type
