OdDbEvalGraph Class

Class Hierarchy

Syntax

C++

class OdDbEvalGraph : public OdDbObject;

File

DbEvalGraph.h

Description

This class implements the behavior of dynamic blocks with a network of interrelated elements.

Remarks

Each element (OdDbEvalExpr object) depends on zero or more other elements. The dependencies are represented as edges to dependent nodes from the nodes on which they depend.

In response to OdDbEvalGraph::evaluate(), this class traverses the graph and invokes OdDbEvalExpr::evaluate() for each of the elements in the graph in the proper order.

Corresponding C++ library: TD_DynBlocks
