Constructor Detail

TypeCasting

protected TypeCasting(TypeDescription typeDescription)

Creates a new type casting.

Parameters:

typeDescription - The type description to which a value should be casted.

Method Detail

to

public static StackManipulation to(TypeDefinition typeDefinition)

Creates a casting to the given, non-primitive type.

Parameters:

typeDefinition - The type to which a value should be casted.

Returns:

A stack manipulation that represents the casting.

isValid

public boolean isValid()

Description copied from interface: StackManipulation

Determines if this stack manipulation is valid.

Specified by:

isValid in interface StackManipulation

Returns:

If false, this manipulation cannot be applied and should throw an exception.

apply

public StackManipulation.Size apply(org.objectweb.asm.MethodVisitor methodVisitor,
                                    Implementation.Context implementationContext)

Description copied from interface: StackManipulation

Applies the stack manipulation that is described by this instance.

Specified by:

apply in interface StackManipulation

Parameters:

methodVisitor - The method visitor used to write the method implementation to.

implementationContext - The context of the current implementation.

Returns:

The changes to the size of the operand stack that are implied by this stack manipulation.
