Modifier and Type	Method	Description
`final <K extends Any, V extends Any> Map<K, V>`	`mapNotNullValues(Pair<K, V> pairs)`	Return a map with only not null values.
`final <T extends Any, K extends Any, V extends Any> List<Pair<K, V>>`	`mapNotNullValues(Iterable<T> $self, Function1<T, Pair<K, V>> transform)`	Map not null values of the Pair results of the specified transformation.
`final <T extends Any> Set<T>`	`toSet(Enumeration<T> $self)`	Extract a Set from an Enumeration.
`final <T extends Any> List<T>`	`toList(Iterator<T> $self)`	Extract a List from an Iterator.
`final <T extends Any> List<T>`	`toSafeList(Iterator<T> $self)`	Extract safely a List from an Iterator - if an [Iterator.next()) call throws an error, ignore this call.
`final <T extends Any> Long`	`sumByLong(Iterable<T> $self, Function1<T, Long> selector)`	Returns the sum of all values produced by selector function applied to each element in the collection.
