Parameters

filter
Type: System::Predicate<Tuple<IList<T1>^, IList<T2>^>^>^

The predicate a value must successfully pass in order for it to be received. filter may be null, in which case all items will pass.

item
Type: System::Tuple<IList<T1>^, IList<T2>^>^

The item received from the source.

Return Value

Type: System::Boolean

true if an item could be received; otherwise, false.

Implements

It will return after checking for an element, whether or not an element was available.
