Interface Assigner

All Known Implementing Classes:

Assigner.EqualTypesOnly, Assigner.Refusing, GenericTypeAwareAssigner, PrimitiveTypeAwareAssigner, ReferenceTypeAwareAssigner, VoidAwareAssigner

public interface Assigner

An assigner is responsible for converting some type A to another type B if possible.

An assigner is for example responsible for type casting, auto boxing or unboxing or for the widening of primitive types.

Nested Class Summary

Nested Classes

Modifier and Type	Interface and Description
static class	Assigner.EqualTypesOnly An assigner that only allows to assign types if they are equal to another.
static class	Assigner.Refusing An assigner that does not allow any assignments.
static class	Assigner.Typing Indicates for a type assignment, if a type casting should be applied in case that two types are not statically assignable.

Field Summary

Fields

Modifier and Type	Field and Description
static Assigner	DEFAULT A default assigner that can handle void, primitive types and reference types which considers generic types as raw types.
static Assigner	GENERICS_AWARE A generics-aware assigner that can handle void, primitive types which reference types.

Field Detail

DEFAULT

static final Assigner DEFAULT

A default assigner that can handle void, primitive types and reference types which considers generic types as raw types.

GENERICS_AWARE

static final Assigner GENERICS_AWARE

A generics-aware assigner that can handle void, primitive types which reference types.

Method Detail

assign

StackManipulation assign(TypeDescription.Generic source,
                         TypeDescription.Generic target,
                         Assigner.Typing typing)

Parameters:

source - The original type that is to be transformed into the targetType.

target - The target type into which the sourceType is to be converted.

typing - A hint whether the assignment should consider the runtime type of the source type, i.e. if type down or cross castings are allowed. If this hint is set, this is also an indication that void to non-void assignments are permitted.

Returns:

A stack manipulation that transforms the sourceType into the targetType if this is possible. An illegal stack manipulation otherwise.
