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

Method Detail

signature

public String signature()

Returns the JNI-style signature for this type.

For primitive classes the returned signature is the signature of the corresponding primitive type; for example, "I" is returned as the signature of the class represented by Integer.TYPE.

Returns:

the string containing the type signature.
