Detailed Description

This class represents application data used during the evaluation of an OdDbEvalGraph object.

Remarks

The graph passes the OdDbEvalContext object passed to OdDbEvalGraph::evaluate() to each node in the graph traversed as a result of calling OdDbEvalExpr::evaluate().

Corresponding C++ library: TD_DynBlocks <group OdDb_Classes>

Member Function Documentation

getAt()

virtual bool OdDbEvalContext::getAt ( OdDbEvalContextPair &  pair ) const

virtual

Returns the ContextPair with the specified key from this Context object.

pair (I/0) Specifies / receives the ContextPair.

Remarks

pair is initialized with the key of the ContextPair to return. If the key exists in this Context object, its associated value replaces the value in the specified ContextPair.

Returns true if and only if the pari exists.

insertAt()

virtual void OdDbEvalContext::insertAt ( const OdDbEvalContextPair &  pair )

virtual

Inserts the specified ContextPair into this Context object.

Parameters

pair	[in] ContextPair to insert.

Remarks

Replaces any ContextPair with the same key.

newIterator()

virtual OdDbEvalContextIteratorPtr OdDbEvalContext::newIterator ( ) const

virtual

Returns an Iterator object that can be used to traverse this Context object.

ODRX_DECLARE_MEMBERS()

OdDbEvalContext::ODRX_DECLARE_MEMBERS

OdDbEvalContext

)

removeAt()

virtual void OdDbEvalContext::removeAt ( const OdString &  key )

virtual

Removes the ContextPair with the specified key from this Context object.

Parameters

key	[in] Key of ContextPair to remove.
