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 |
---|---|

double |
DoubleType |

Method Details
-
signature
String signature()Returns the type signature for this type. The result is of the same form as the string returned byClass.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 byClass.getName()
. The returned name may not be a binary name.- Returns:
- the name of this type
-
