Method Detail

create

public static <T,R> ResolvedStaticAttribute<T> create(StaticAttribute<T,R> staticAttribute,
                                                      AttributeType<R> attributeType)

transform

public <R> ResolvedStaticAttribute<R> transform(Function<R,T> transform,
                                                Consumer<R> createComponent)

Return a transformed copy of this attribute that knows how to get/set from a different type of object given a function that can convert the containing object itself. It does this by modifying the get/set functions of type T to type R given a transformation function F(T) = R.

Type Parameters:

R - The type being transformed to.

Parameters:

transform - A function that converts the object storing the attribute from the source type to the destination type.

createComponent - A consumer to create a new instance of the component object when required. A null value will bypass this logic.

Returns:

A new Attribute that be contained by an object of type R.
