OdUInt8 flags |
[in] Flag bits. |
|
OdDbGraphNodeArray* pNodeArray = 0 |
[in] Pointer to a GraphNode array. |
Marks this GraphNode object and all nested outgoing GraphNode objects with the specified flags.

The user must clear the flags with OdDbGraph::clearAll() or OdDbGraphNode::clear() when done with them.
flags must be a combination of one or more of the following:
