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.

getOpcode

protected abstract int getOpcode()

Returns the opcode for implementing the field access.

Returns:

The opcode for implementing the field access.

resolveSize

protected abstract StackManipulation.Size resolveSize(StackSize fieldSize)

Resolves the actual size of this field access operation.

Parameters:

fieldSize - The size of the accessed field.

Returns:

The size of the field access operation based on the field's size.
