Methods
trySplit
Spliterator.OfLong trySplit()
Description copied from interface: Spliterator
If this spliterator can be partitioned, returns a Spliterator covering elements, that will, upon return from this method, not be covered by this Spliterator.
If this Spliterator is Spliterator.ORDERED
, the returned Spliterator must cover a strict prefix of the elements.
Unless this Spliterator covers an infinite number of elements, repeated calls to trySplit()
must eventually return null
. Upon non-null return:
- the value reported for
estimateSize()
before splitting, must, after splitting, be greater than or equal toestimateSize()
for this and the returned Spliterator; and - if this Spliterator is
SUBSIZED
, thenestimateSize()
for this spliterator before splitting must be equal to the sum ofestimateSize()
for this and the returned Spliterator after splitting.
This method may return null
for any reason, including emptiness, inability to split after traversal has commenced, data structure constraints, and efficiency considerations.
- Specified by:
-
trySplit
in interfaceSpliterator<Long>
- Specified by:
-
trySplit
in interfaceSpliterator.OfPrimitive<Long,LongConsumer,Spliterator.OfLong>
- Returns:
- a
Spliterator
covering some portion of the elements, ornull
if this spliterator cannot be split
tryAdvance
boolean tryAdvance(LongConsumer action)
Description copied from interface: Spliterator.OfPrimitive
If a remaining element exists, performs the given action on it, returning true
; else returns false
. If this Spliterator is Spliterator.ORDERED
the action is performed on the next element in encounter order. Exceptions thrown by the action are relayed to the caller.
- Specified by:
-
tryAdvance
in interfaceSpliterator.OfPrimitive<Long,LongConsumer,Spliterator.OfLong>
- Parameters:
-
action
- The action - Returns:
-
false
if no remaining elements existed upon entry to this method, elsetrue
.
forEachRemaining
default void forEachRemaining(LongConsumer action)
Description copied from interface: Spliterator.OfPrimitive
Performs the given action for each remaining element, sequentially in the current thread, until all elements have been processed or the action throws an exception. If this Spliterator is Spliterator.ORDERED
, actions are performed in encounter order. Exceptions thrown by the action are relayed to the caller.
- Specified by:
-
forEachRemaining
in interfaceSpliterator.OfPrimitive<Long,LongConsumer,Spliterator.OfLong>
- Parameters:
-
action
- The action
tryAdvance
default boolean tryAdvance(Consumer<? super Long> action)
If a remaining element exists, performs the given action on it, returning true
; else returns false
. If this Spliterator is Spliterator.ORDERED
the action is performed on the next element in encounter order. Exceptions thrown by the action are relayed to the caller.
- Specified by:
-
tryAdvance
in interfaceSpliterator<Long>
- Implementation Requirements:
- If the action is an instance of
LongConsumer
then it is cast toLongConsumer
and passed totryAdvance(java.util.function.LongConsumer)
; otherwise the action is adapted to an instance ofLongConsumer
, by boxing the argument ofLongConsumer
, and then passed totryAdvance(java.util.function.LongConsumer)
. - Parameters:
-
action
- The action - Returns:
-
false
if no remaining elements existed upon entry to this method, elsetrue
.
forEachRemaining
default void forEachRemaining(Consumer<? super Long> action)
Performs the given action for each remaining element, sequentially in the current thread, until all elements have been processed or the action throws an exception. If this Spliterator is Spliterator.ORDERED
, actions are performed in encounter order. Exceptions thrown by the action are relayed to the caller.
- Specified by:
-
forEachRemaining
in interfaceSpliterator<Long>
- Implementation Requirements:
- If the action is an instance of
LongConsumer
then it is cast toLongConsumer
and passed toforEachRemaining(java.util.function.LongConsumer)
; otherwise the action is adapted to an instance ofLongConsumer
, by boxing the argument ofLongConsumer
, and then passed toforEachRemaining(java.util.function.LongConsumer)
. - Parameters:
-
action
- The action
