Method Detail

push

protected void push(StackFrame frame,
        ElementInfo e,
        int index)
             throws ArrayIndexOutOfBoundsExecutiveException

Specified by:

push in class ArrayLoadInstruction

Throws:

ArrayIndexOutOfBoundsExecutiveException

getElementSize

protected int getElementSize()

Description copied from class: ArrayElementInstruction

return size of array elements in stack words (long,double: 2, all other: 1) e.g. used to determine where the object reference is on the stack should probably be abstract, but there are lots of subclasses and only LongArrayLoad/Store insns have different size

Overrides:

getElementSize in class ArrayElementInstruction

accept

public void accept(InstructionVisitor insVisitor)

Specified by:

accept in interface InstructionVisitorAcceptor

Overrides:

accept in class ArrayLoadInstruction
