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 --
| 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 |
| 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

Methods
| Modifier and Type | Method | Description |
|---|---|---|
String | name() | |
String | signature() | Returns the JNI-style signature for this type. |
Methods declared in interface com.sun.jdi.Mirror
toString, virtualMachine Methods
signature
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.
- See Also:
- Type Signatures
name
String name()
- Returns:
- a text representation of this type.
