Method details

A IDirectedCollectionValue<T> Backwards()

Returns:

bool FindLast(Fun<T,bool> predicate, out T item)

Check if there exists an item that satisfies a specific predicate in this collection and return the first one in enumeration order.

Returns:	True is such an item exists
Parameters:
predicate:	A delegate (Fun<A1,R> with `R == bool`) defining the predicate
item:
