count

abstract fun count(element: @UnsafeVariance E): Int(source)

Returns the number of occurrences of an element in this multiset (the count of the element). Note that for an Object.equals-based multiset, this gives the same result as Collections.frequency (which would presumably perform more poorly).

Note: the utility method Iterables.frequency generalizes this operation; it correctly delegates to this method when dealing with a multiset, but it can also accept any other iterable type.

Return

the number of occurrences of the element in this multiset; possibly zero but never negative

Parameters

element

the element to count occurrences of
