DoubleSequence into an array.default DoubleSequence prefix(double... xs)
DoubleSequence with the given doubles.default DoubleSequence suffix(double... xs)
DoubleSequence with the given doubles.default DoubleSequence interleave(DoubleIterable that)
DoubleSequence with those of the given DoubleIterable, stopping
when either sequence finishes.default DoubleSequence reverse()
DoubleSequence which iterates over this DoubleSequence in reverse order.sorted()default DoubleSequence mapBack(double firstPrevious, java.util.function.DoubleBinaryOperator mapper)
DoubleSequence to another sequence of doubles while peeking at the previous value in the
sequence.
The mapper has access to the previous double and the current double in the iteration. If the current double is the first value in the sequence, and there is no previous value, the provided replacement value is used as the first previous value.
default DoubleSequence mapForward(double lastNext, java.util.function.DoubleBinaryOperator mapper)
DoubleSequence to another sequence of doubles while peeking at the next value in the
sequence.
The mapper has access to the current double and the next double in the iteration. If the current double is the last value in the sequence, and there is no next value, the provided replacement value is used as the last next value.

default Sequence<DoubleSequence> window(int window)
DoubleSequence into a sequence of DoubleSequences of elements, each
with
the size of the given window. The first item in each list is the second item in the previous list. The final
DoubleSequence may be shorter than the window. This is equivalent to window(window, 1).default Sequence<DoubleSequence> window(int window, int step)
DoubleSequence into a sequence of DoubleSequences of elements, each
with
the size of the given window, stepping step elements between each window. If the given step is less than
the window size, the windows will overlap each other.default Sequence<DoubleSequence> batch(int size)
DoubleSequence into a sequence of DoubleSequences of distinct
elements,
each with the given batch size. This is equivalent to window(size, size).default Sequence<DoubleSequence> batch(DoubleBiPredicate predicate)
DoubleSequence into a sequence of DoubleSequences of distinct
elements,
where the given predicate determines where to split the lists of partitioned elements. The predicate is given
the current and next item in the iteration, and if it returns true a partition is created between the elements.default Sequence<DoubleSequence> split(double element)
doubles of this DoubleSequence into a sequence of DoubleSequences of distinct
elements, around the given double. The elements around which the sequence is split are not included in
the result.default Sequence<DoubleSequence> split(java.util.function.DoublePredicate predicate)
doubles of this DoubleSequence into a sequence of DoubleSequences of distinct
elements, where the given predicate determines which doubles to split the partitioned elements around.
The
doubles matching the predicate are not included in the result.default void clear()

DoubleSequence is empty, false otherwise.default boolean contains(double d,
double precision)
DoubleSequence contains the given double, false otherwise.default boolean containsAll(double precision,
double... items)
DoubleSequence contains all of the given doubles compared to the given
precision, false otherwise.default boolean containsAny(double precision,
double... items)
DoubleSequence contains any of the given doubles, false otherwise.default void forEachDoubleIndexed(DoubleLongConsumer action)
double in this DoubleSequence, with the index of each element passed
as the second parameter in the action.
