public class Variables
extends java.lang.Object

This class contains a set of temporary variables which may be used freely in methods which receive an instance of Variables as argument. The sole requirement is that the size of the int-stack is restored to its value before method invocation.

Method Detail

getISize

public int getISize()

ienter

public int ienter(int size)

This method increases the size of the int-stack istack by size and returns the previous size of the stack.

Parameters:

size - size increment

Returns:

previous value of stack size

See Also:

getISize()

ipop

public int ipop()

This method pops the topmost element off the int-stack istack and returns its value.

Returns:

popped element

ipush

public void ipush(int value)

This method pushs a new value on the int-stack istack.

Parameters:

value - value to push

setISize

public void setISize(int isize)

This method sets the size of the int-stack istack to isize. The array is enlarged if necessary.

Parameters:

isize - new size of stack
