default DoublePredicate |
DoublePredicate.and(DoublePredicate other) |
Returns a composed predicate that represents a short-circuiting logical
AND of this predicate and another.
|
default DoublePredicate |
DoublePredicate.negate() |
Returns a predicate that represents the logical negation of this
predicate.
|
default DoublePredicate |
DoublePredicate.or(DoublePredicate other) |
Returns a composed predicate that represents a short-circuiting logical
OR of 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.
|
default 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 |
DoubleStream.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.
|
default 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.
