OdDbEvalGraph::evaluate Method ()
Syntax
C++
virtual bool evaluate() const;

Returns true if and only if successful.

Evaluates this Graph object.

Evaluation is accomplished by traversing the activated nodes on the Graph, invoking OdDbEvalExpr::evaluate() on each of the visited nodes. 

Nodes may be activated with either the activate() method, or by supplying an activatedNodes argument. 

Nodes not activated are deactivated.
