CSimpleRow Class

Provides a default implementation for the row handle, which is used in the IRowsetImpl class.

class CSimpleRow

Members

Methods

AddRefRow	Adds a reference count to an existing row handle.
Compare	Compares two rows to see if they refer to the same row instance.
CSimpleRow	The constructor.
ReleaseRow	Releases rows.

Data Members

m_dwRef	Reference count to an existing row handle.
m_iRowset	An index to the rowset representing the cursor.

Remarks

A row handle is logically a unique tag for a result row. IRowsetImpl creates a new CSimpleRow for every row requested in IRowsetImpl::GetNextRows. CSimpleRow can also be replaced with your own implementation of the row handle, as it is a default template argument to IRowsetImpl. The only requirement to replacing this class is to have the replacement class provide a constructor that accepts a single parameter of type LONG.
