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
