Functional interfaces provide target types for lambda expressions
and method references.
|

LongPredicates.and(LongPredicate this_,
LongPredicate other)
Returns a composed predicate that represents a short-circuiting logical
AND of the

this_
predicate. |
static LongPredicate |
LongPredicates.or(LongPredicate this_,
LongPredicate other)
Returns a composed predicate that represents a short-circuiting logical
OR of the
this_ predicate and another. |

boolean |
LongStream.allMatch(LongPredicate predicate)
Returns whether all elements of this stream match the provided predicate.
|
boolean |
LongStream.anyMatch(LongPredicate predicate)
Returns whether any elements of this stream match the provided
predicate.
|
LongStream |
LongStream.dropWhile(LongPredicate predicate)
Returns, if this stream is ordered, a stream consisting of the remaining
elements of this stream after dropping the longest prefix of elements
that match the given predicate.
|
static LongStream |
LongStreams.dropWhile(LongStream stream,
LongPredicate predicate)
Returns a stream consisting of the remaining elements of the passed
stream after discarding elements that match the given predicate up to,
but not discarding, the first element encountered that does not match
the predicate.
|
LongStream |
LongStream.filter(LongPredicate predicate)
Returns a stream consisting of the elements of this stream that match
the given predicate.
|
static LongStream |
LongStreams.iterate(long seed,
LongPredicate hasNext,
LongUnaryOperator next)
Returns a sequential ordered
LongStream produced by iterative
application of the given next function to an initial element,
conditioned on satisfying the given hasNext predicate. |
boolean |
LongStream.noneMatch(LongPredicate predicate)
Returns whether no elements of this stream match the provided predicate.
|
LongStream |
LongStream.takeWhile(LongPredicate predicate)
Returns, if this stream is ordered, a stream consisting of the longest
prefix of elements taken from this stream that match the given predicate.
|
static LongStream |
LongStreams.takeWhile(LongStream stream,
LongPredicate predicate)
Returns a stream consisting of elements of the passed stream that match
the given predicate up to, but discarding, the first element encountered
that does not match the predicate.
