Provides the underlying implementation for the GetValue method.

Pascal
function ImplGetValue: Variant; override;
C++
virtual __fastcall Variant ImplGetValue();
Description

GetValue calls ImplGetValue to obtain the value of the adapter field as a Variant. 

ImplGetValue first generates an OnGetValue event, to allow an event handler to supply the value of the field. If there is no OnGetValue event handler, ImplGetValue calls the GetDataSetFieldValue method, which returns the value of the associated dataset field. If ImplGetValue can't locate the dataset field from which to obtain a value, it returns an unassigned Variant.
