Detailed Description

A visitor for building a SmCaretPosGraph.

Visit invariant: Each pNode, except SmExpressionNode, SmBinHorNode and a few others, constitutes an entry in a line. Consider the line entry "H", this entry creates one carat position, here denoted by | in "H|".

Parameter variables: The following variables are used to transfer parameters into calls and results out of calls. pRightMost : SmCaretPosGraphEntry*

Prior to a Visit call: pRightMost: A pointer to right most position in front of the current line entry.

After a Visit call: pRightMost: A pointer to the right most position in the called line entry, if no there's no caret positions in called line entry don't change this variable.

SmErrorNode is context dependent metadata, it can't be selected.

Remarks: There's no point in deleting, copying and/or moving an instance of SmErrorNode as it may not exist in another context! Thus there are no positions to select an SmErrorNode.

void SmCaretPosGraphBuildingVisitor::Visit ( SmOperNode * pNode )

overridevirtual

Build caret position for SmOperNode.

If first child is an SmSubSupNode we will ignore its body, as this body is a SmMathSymbol, for SUM, INT or similar that shouldn't be subject to modification. If first child is not a SmSubSupNode, ignore it completely as it is a SmMathSymbol.

The child positions in a SmOperNode, where H is symbol, e.g. int, sum or similar:

      TO
 
LSUP H  H RSUP    BBB    BB  BBB  B   B
     H  H         B  B  B  B B  B  B B
     HHHH         BBB   B  B B  B   B
     H  H         B  B  B  B B  B   B
LSUB H  H RSUB    BBB    BB  BBB    B
 
     FROM

Notice, CSUP, etc. are actually grandchildren, but inorder to ignore H, these are visited from here. If they are present, that is if pOper is an instance of SmSubSupNode.
