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 --

Method Details
-
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.

name
String name()- Returns:
- a text representation of this type.
