Detailed Description

An object of this class will update a a2dIterC with the required information.

As iteration goes down the child hierarchy, a a2dIterCU is created to update a a2dIterC. It will update the parent list as well as the matrix

Assume the following object tree

     A
   /   \
  B     C
 / \   / \
D   E F   G

The constructors / destructors are called in the following order, and the values of GetParent and GetPreviousSibling, GetPreviousOrParent and GetPreviousDeep are shown (time is going from left to right):

Const:    A   B   D       E           C   F       G   
Destr:                D       E   B           F       G   C   A

Parent: X   0   A   B   A   B   A   0   A   C   A   C   A   0   X

PrevSi: X   0   0   0   0   D   0   0   B   0   B   F   B   0   X

PrevOP: X   0   A   B   A   D   A   0   B   C   B   F   B   0   X

PrevD:  X   0   0   0   D   D   E   B   B   B   F   F   G   C   A

Stack:  -   A   A   A   A   A   A   A   A   A   A   A   A   A   -
        -   -   B   B   B   B   B   -   C   C   C   C   C   -   -

Constructor & Destructor Documentation

a2dIterCU::a2dIterCU	(	a2dIterC &	ic,
		a2dCanvasObject *	object,
		OVERLAP	clip = _IN
	)

Update iteration context.

Create an object of this type locally in a a2dCanvasObject child tree iteration function at each recusion level. This will update the iteration context and restore it later
