Parameters
nameName of the data object.

Member Function Documentation

virtual Type kanzi::DataObjectList::getType ( ) const
inlinevirtual

Retrieves the type of this data object.

Returns
Type enumeration of this data object.

Reimplemented from kanzi::DataObject.

virtual size_t kanzi::DataObjectList::itemCount ( )
pure virtual
virtual DataObjectSharedPtr kanzi::DataObjectList::acquireItem ( size_t  index)
pure virtual
virtual void kanzi::DataObjectList::releaseItem ( size_t  index)
