Package com.g2forge.alexandria.java.type.ref

Interface ITypeRef<T>

Type Parameters:

T - The (static) type of this type reference.

All Superinterfaces:

IDynamicType<T>

All Known Implementing Classes:

ATypeRef, ATypeRefIdentity, ITypeRef.ClassTypeRef

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ITypeRef<T>
extends IDynamicType<T>

Captures the relationship between the static type T and the runtime type getType(). Due to the lack of proper generic support in the Java reflection library, this interface is currently not statically type safe. As such implementors are responsible for type safety.

Method Detail

of

static <T> ITypeRef<T> of(Class<T> type)

Construct an instance of ITypeRef for a Java Class. This is most useful for non-parameterized classes.

Type Parameters:

T - The (static) type of the resulting type reference.

Parameters:

type - The class to create a reference to.

Returns:

An instance of ITypeRef whose getType() returns type.

cast

default T cast(Object value)

Specified by:

cast in interface IDynamicType<T>

getErasedType

default Class<T> getErasedType()

getType

Type getType()

Get the dynamic (runtime) type of T.

Returns:

The dynamic (runtime) type of T.
