virtual OdResult OdDbObjectContextInterface::addContext ( OdDbObject *  pObject, const OdDbObjectContext &  context  ) const

pure virtual

Adds a context to the specified object.

\param pObject [in]  Pointer to the object.
\param context [in]  Name of the context to add.

\returns
Returns eOk if successful, or an appropriate error code if not.

Implemented in OdDbObjectContextAttributePE, OdDbObjectContextHatchPE, OdDbObjectContextDimPE, OdDbObjectContextBlkRefPE, OdDbObjectContextMLeaderPE, OdDbObjectContextPE, and OdDbObjectContextDefaultPE.

hasContext()

virtual bool OdDbObjectContextInterface::hasContext ( const OdDbObject *  pObject, const OdDbObjectContext &  context  ) const

pure virtual

Returns whether a context is used by a specified object.

\param pObject [in]  Pointer to the object.
\param context [in]  Name of the context.

\returns
Returns true if the object uses the named context, or returns
false if it does not.

Implemented in OdDbObjectContextPE, and OdDbObjectContextDefaultPE.

supportsCollection()

virtual bool OdDbObjectContextInterface::supportsCollection ( const OdDbObject *  pObject, const OdString &  collectionName  ) const

pure virtual

Returns whether a context collection is supported by a specified object.

\param pObject [in]  Pointer to the object.
\param collectionName [in]  Name of the context collection.

\returns
