static DoublePredicate |
DoublePredicates.and(DoublePredicate this_,
DoublePredicate other)
Returns a composed predicate that represents a short-circuiting logical
AND of the

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

boolean |
DoubleStream.allMatch(DoublePredicate predicate)
Returns whether all elements of this stream match the provided predicate.
|
boolean |
DoubleStream.anyMatch(DoublePredicate predicate)
Returns whether any elements of this stream match the provided
predicate.
|
DoubleStream |
DoubleStream.dropWhile(DoublePredicate 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.
|
DoubleStream |
DoubleStream.filter(DoublePredicate predicate)
Returns a stream consisting of the elements of this stream that match
the given predicate.
|
static DoubleStream |
DoubleStreams.iterate(double seed,
DoublePredicate hasNext,
DoubleUnaryOperator next)
Returns a sequential ordered
DoubleStream produced by iterative
application of the given next function to an initial element,
conditioned on satisfying the given hasNext predicate. |
boolean |
DoubleStream.noneMatch(DoublePredicate predicate)
Returns whether no elements of this stream match the provided predicate.
|
DoubleStream |
DoubleStream.takeWhile(DoublePredicate 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.
