Class Type<T>

java.lang.Object
  ma.glasnost.orika.metadata.Type<T>

Type Parameters:

T -

All Implemented Interfaces:

Comparable<Type<?>>, ParameterizedType, Type

public final class Type<T>
extends Object
implements ParameterizedType, Comparable<Type<?>>

Type is an implementation of ParameterizedType which may be used in various mapping methods where a Class instance would normally be used, in order to provide more specific details as to the actual types represented by the generic template parameters in a given class.

Such details are not normally available at runtime using a Class instance due to type-erasure.

Type essentially provides a runtime token to represent a ParameterizedType with fully-resolve actual type arguments; it will contain
