Constructor Detail

OffsetIncrementing

protected OffsetIncrementing(int offset,
                             int value)

Creates a new argument loading stack manipulation.

Parameters:

offset - The index of the local variable array from which the variable should be loaded.

value - The value to increment.

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:
