Summary
Inherited constants |
|---|
From
interface
java.util.Spliterator
int |
CONCURRENT
Characteristic value signifying that the element source may be safely
concurrently modified (allowing additions, replacements, and/or removals)
by multiple threads without external synchronization.
|
int |
DISTINCT
Characteristic value signifying that, for each pair of
encountered elements x, y, !x.equals(y).
|
int |
IMMUTABLE
Characteristic value signifying that the element source cannot be
structurally modified; that is, elements cannot be added, replaced, or
removed, so such changes cannot occur during traversal.
|
int |
NONNULL
Characteristic value signifying that the source guarantees that
encountered elements will not be null.
|
int |
ORDERED
Characteristic value signifying that an encounter order is defined for
elements.
|
int |
SIZED
Characteristic value signifying that the value returned from
estimateSize() prior to traversal or splitting represents a
finite size that, in the absence of structural source modification,
represents an exact count of the number of elements that would be
encountered by a complete traversal.
|
int |
SORTED
Characteristic value signifying that encounter order follows a defined
sort order.
|
int |
SUBSIZED
Characteristic value signifying that all Spliterators resulting from
trySplit() will be both SIZED and SUBSIZED.

trySplit
Spliterator.OfDouble 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:
- the value reported for
estimateSize() before splitting,
must, after splitting, be greater than or equal to estimateSize()
for this and the returned Spliterator; and
- if this Spliterator is
SUBSIZED, 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 |

Spliterator.OfDouble |
a Spliterator covering some portion of the
elements, or null if this spliterator cannot be split
