Public Interface IPairFilter(Of T)

generic<typename T>
public interface class IPairFilter

Type Parameters

A IPairFilter<(Of <(<'T>)>)> is usually used to remove item pairs, so that they are not processed. Filter(Pair<(Of <<'(T>)>>)) returns trueTruetruetrue (True in Visual Basic) if an item pair should be processed (item pair is accepted). Filter(Pair<(Of <<'(T>)>>)) returns falseFalsefalsefalse (False in Visual Basic) if an item pair should not be processed (item pair is rejected).

Notes to Implementors: The filter rules must be consistent. In most applications the order of the items in the pair should not matter. And Filter(Pair<(Of <<'(T>)>>)) should always return the same result for the same pair. If the filter rules are changed, the Changed event must be raised.
