Summary
Base implementation for the IJvDataContext interface.
Pascal
run\JvDataProvider.pas
TJvBaseDataContext = class(TExtensibleInterfacedPersistent, IJvDataContext);
Description
The TJvBaseDataContext class is the base implementer for the IJvDataContext interface. The class itself only provides an implementation for the IJvDataContext methods with an exception of the Name method.
The class provides in an implementation for the SetName method of the IJvDataContextManager class, but that interface is not supported directly. The implementation of this method will check if the new name is unique in the context list and raise an exception if that's not the case. If the name is unique it will call the (abstract) DoSetName method to actually set the new name.
You should never instantiate a TJvBaseDataContext object to provide an implementation for the IJvDataContext interface. Instead you should use a derivative that implements the Name method, such as the TJvDataContext class.
