Description
This class implements a simple container for application data that can be used during the evaluation of an AcDbEvalGraph. The graph passes any AcDbEvalContext object supplied in a call to AcDbEvalGraph::evaluate() to each node in the graph when calling AcDbEvalExpr::evaluate() during the ensuing traversal. Graph client applications typically use the context to store application-specific data used by custom nodes during their evaluation.
