Nested and Inner Type Summary

Modifier and TypeClass and Description
pack-priv static interface
WhileOps.DropWhileOp<
the type of both input and output elements
T>

A specialization for the dropWhile operation that controls if elements to be dropped are counted and passed downstream.

pack-priv static interface
WhileOps.DropWhileSink<
the type of both input and output elements
T>

A specialization for a dropWhile sink.

private static class
WhileOps.DropWhileTask<
Input element type to the stream pipeline
P_IN,
Output element type from the stream pipeline
P_OUT>

ForkJoinTask implementing dropWhile computation.

private static class
WhileOps.TakeWhileTask<
Input element type to the stream pipeline
P_IN,
Output element type from the stream pipeline
P_OUT>

ForkJoinTask implementing takeWhile computation.

pack-priv abstract static class
WhileOps.UnorderedWhileSpliterator<
the type of elements returned by this spliterator
T,
the type of the spliterator
T_SPLITR extends Spliterator<T>>

A spliterator supporting takeWhile and dropWhile operations over an underlying spliterator whose covered elements have no encounter order.
