void forEachRemaining (T_CONS 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 ORDERED
,
actions are performed in encounter order. Exceptions thrown by the
action are relayed to the caller.
tryAdvance(T_CONS)
until it returns false
. It should be overridden whenever
possible.Parameters | |

boolean tryAdvance (T_CONS action)
If a remaining element exists, performs the given action on it,
returning true
; else returns false

Spliterator is ORDERED
the action is performed on the
next element in encounter order. Exceptions thrown by the
action are relayed to the caller.

T_SPLITR trySplit ()
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 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:
estimateSize()
before splitting,
must, after splitting, be greater than or equal to estimateSize()
for this and the returned Spliterator; andSUBSIZED
, then estimateSize()
for this spliterator before splitting must be equal to the sum of
estimateSize()
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.
Returns | |
---|---|
T_SPLITR |
a Spliterator covering some portion of the
elements, or null if this spliterator cannot be split
