Méthodes protégées

Méthode Description
Dispose ( bool disposing ) : void

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
Initialize ( ) : void

Initializes this instance.
LeftOrphanRow ( FdoRow row ) : void

Called when a row on the left side was filtered by the join condition, allow a derived class to perform logic associated to that, such as logging
MergeRows ( FdoRow leftRow, FdoRow rightRow ) : FdoRow

Merges the two rows into a single row
RightOrphanRow ( FdoRow row ) : void

Called when a row on the right side was filtered by the join condition, allow a derived class to perform logic associated to that, such as logging
SetupJoinConditions ( ) : void

Setups the join conditions.
