TObject |
The TBinaryObjectReader class reads component data stored in binary form in a file. For this, it overrides or implements all abstract methods from TAbstractObjectReader. No new functionality is added by this class, it is a driver class for the streaming system.
It should never be necessary to create an instance of this class directly. Instead, the TStream.WriteComponent call should be used.
