Detailed Description

A universal driver for the attribute that inherits another attribute with ready to used persistence mechanism implemented (already has a driver to store/retrieve).

Constructor & Destructor Documentation

◆ BinMDF_DerivedDriver()

BinMDF_DerivedDriver::BinMDF_DerivedDriver ( const Handle< TDF_Attribute > &  theDerivative,
const Handle< BinMDF_ADriver > &  theBaseDriver 
)
inline

Creates a derivative persistence driver for theDerivative attribute by reusage of theBaseDriver.

Parameters
theDerivativean instance of the attribute, just created, detached from any label
theBaseDrivera driver of the base attribute, called by Paste methods
