OdDbEvalExpr Class

Syntax

C++

class OdDbEvalExpr : public OdDbObject;

Description

This class represents single nodes in OdDbEvalGraph objects.

Remarks

Each node reprsents an action or expression. The OdDbEvalGraph object calls each owned node's evaluate() method while traversing the graph within the OdDbEvalGraph::evaluate() method.

Corresponding C++ library: TD_DynBlocks
