public class Variables extends 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.

    • getISize

      public int getISize()

    • 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

    • ipush

      public void ipush(int value)
      This method pushs a new value on the int-stack istack.
      Parameters:
      value - value to push

    • ipop

      public int ipop()
      This method pops the topmost element off the int-stack istack and returns its value.
      Returns:
      popped element

    • 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
