Method Detail

getStackChange

public int getStackChange()

Description copied from class: Instruction

Return the number of stack positions this instruction pushes or pops during its execution.

Overrides:

getStackChange in class Instruction

Tags copied from class: Instruction

Returns:

0 if the stack is not affected by this instruction, a positive number if it pushes onto the stack, and a negative number if it pops from the stack

equals

public boolean equals(Object other)

Description copied from class: ArrayInstruction

Two array instructions are equal if the index and type they reference are equal or if either index is 0/unset.

Overrides:

equals in class ArrayInstruction

calculateOpCode

protected void calculateOpCode()

Description copied from class: ArrayInstruction

Subclasses with variable opcodes can use this method to be notified that information possibly affecting the opcode has been changed.

Overrides:

calculateOpCode in class ArrayInstruction
