template <class T, class BindType = ATLBINDINGS, class BindingVector = CSimpleMap < int, BindType* > >
class ATL_NO_VTABLE IAccessorImpl : public IAccessorImplBase<BindType>
Parameters
T
Your rowset or command object class.
BindType
Storage unit for binding information.
BindingVector
Storage unit for column information.
Remarks
This is mandatory on rowsets and commands. Provides an implementation of the IAccessor interface. OLE DB requires providers to implement an HACCESSOR, which is a tag to an array of DBBINDING structures. HACCESSORs provided by IAccessorImpl are addresses of the BindType structures. By default, BindType is defined as an ATLBINDINGS in IAccessorImpl’s template definition. BindType provides a mechanism used by IAccessorImpl to track the number of elements in its DBBINDING array as well as a reference count and accessor flags.
