Facade constructor.

Method Details

apply

void apply(Map<String,TypeFacade<?,?>> typeArguments)

Applies type arguments.

This is typically done after sealing original type parameters to apply the resulting parameters as arguments to the next reference.

Parameters:

typeArguments - Type arguments to apply. Expects arguments to be applied in highest-order last; type arguments matching the name of a previously applied argument will be overridden.

apply

void apply(AnnotatedElementBase<?> referrer,
 TypeVariable<?> typeVariable,
 Type actualTypeArgument)

Applies a type argument from a parameterized type.

Parameters:

referrer - element referring to the parameterized type, typically its TypeTemplate.

typeVariable - type variable declared by raw type erasure.

actualTypeArgument - from ParameterizedType.getActualTypeArguments() relative to position of typeVariable.

seal

void seal(GenericDeclaration genericDeclaration,
 AnnotatedElementBase<?> referrer)

Seals type parameters from incoming arguments based on a generic declaration.

Parameters:

genericDeclaration - source element capable of declaring type parameters

referrer - referring element to use with any type parameters generated from genericDeclaration
