Constructor Detail

WideningStackManipulation

protected WideningStackManipulation(int conversionOpcode,
                                    StackManipulation.Size size)

Creates a new widening stack manipulation.

Parameters:

conversionOpcode - The opcode for executing the conversion.

size - The size change of applying the conversion.

Method Detail

isValid

public boolean isValid()

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)

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.
