Class VoidAwareAssigner

java.lang.Object

net.bytebuddy.implementation.bytecode.assign.primitive.VoidAwareAssigner

All Implemented Interfaces:

Assigner

@Enhance
public class VoidAwareAssigner
extends Object
implements Assigner

This assigner is able to handle the void type. This means:

1. If a void type is assigned to the void it will consider this a trivial operation.
2. If a void type is assigned to a non-void type, it will pop the top value from the stack.
3. If a non-void type is assigned to a void type, it will load the target type's default value only if this was configured at the assigner's construction.
4. If two non-void types are subject of the assignment, it will delegate the assignment to its chained assigner.

Constructor Details

VoidAwareAssigner

public VoidAwareAssigner(Assigner chained)

Creates a new assigner that is capable of handling void types.

Parameters:

chained - A chained assigner which will be queried by this assigner to handle assignments that do not involve a void type.

Method Details

assign

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

Specified by:

assign in interface Assigner

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.
