Type (Java Debug Interface )

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

@Exported
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 table illustrates 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		`ArrayType`
an array	`int[]`	`ArrayType` whose `componentType()` is `IntegerType`
an array	`Date[]`	`ArrayType` whose `componentType()` is `ClassType`
an array	`Runnable[]`	`ArrayType` whose `componentType()` is `InterfaceType`
