BCGSuite for MFC
CBCGPOutlineNode

Detailed Description

The CBCGPOutlineNode class is used with CBCGPEditCtrl and CBCGPOutlineParser classes.

It represents an hierarchy of outlining nodes and the data structure for collapsible node itself. It contains a list of sub nodes and a pointer to parent node.

The root of the hierarchy tree is the node that meets the following conditions: parent node is NULL, m_nStart is -1, m_nEnd is -1. The CBCGPEditCtrl class contains the root of the hierarchy tree for all collapsible nodes.

Each node has a list of sub nodes:

  • Sub nodes are sorted by their offsets from the beginning of the edit control's text buffer.
  • Intersection of collapsible nodes is not allowed.
  • Parent node covers all sub nodes. A sub node should be inside its parent node.

All these conditions are verified while new nodes are being added. Note, that if you add a new node, which intersects some of existing nodes, then all intersected nodes are removed.
