combineCollection

public static <T,C extends Collection<T>> java.util.stream.Collector<C,?,C> combineCollection(java.util.function.Supplier<C> collectionFactory)

Returns a Collector that accumulates the input elements into a new Collection, in encounter order. The Collection is created by the provided factory.

Type Parameters:

T - the collection type of the input elements

C - the type of the resulting Collection

Parameters:

collectionFactory - a Supplier which returns a new, empty Collection of the appropriate type

Returns:

a Collector which collects all the input elements into a Collection, in encounter order

combineList

public static <T> java.util.stream.Collector<List<T>,?,List<T>> combineList()

Returns a Collector that accumulates the input list elements into a new List. There are no guarantees on the type, mutability, serializability, or thread-safety of the List returned; if more control over the returned List is required, use

Type Parameters:

T - the collection type of the input elements

Returns:

a Collector which collects all the input elements into a List, in encounter order

collectList

public static <T,A> java.util.stream.Collector<T,List<A>,List<A>> collectList(java.util.function.BiConsumer<List<A>,T> consumer)

Returns a Collector that accumulates the input list elements into a new List. There are no guarantees on the type, mutability, serializability, or thread-safety of the List returned; if more control over the returned List is required, use

Type Parameters:

T - the type of the input elements

A - the type of the output element

Parameters:

consumer - accumulator of collector

Returns:

a Collector which collects all the transformed elements into a List, in encounter order
