Field Details

EMPTY

static final CloseablePrimitiveIteratorOfDouble EMPTY

A re-usable, immutable CloseablePrimitiveIteratorOfDouble with no elements.

Method Details

doubleStream

default DoubleStream doubleStream()

Create a DoubleStream over the remaining elements of this CloseablePrimitiveIteratorOfDouble. Closing the result will close this CloseablePrimitiveIteratorOfDouble.

Returns:

A DoubleStream over the remaining contents of this iterator

empty

static CloseablePrimitiveIteratorOfDouble empty()

Get a CloseablePrimitiveIteratorOfDouble with no elements. The result does not need to be closed.

Returns:

A CloseablePrimitiveIteratorOfDouble with no elements

of

static CloseablePrimitiveIteratorOfDouble of(@NotNull
 @org.jetbrains.annotations.NotNull double... values)

Create a CloseablePrimitiveIteratorOfDouble over an array of double. The result does not need to be closed.

Parameters:

values - The elements to iterate

Returns:

A CloseablePrimitiveIteratorOfDouble of values

repeat

static CloseablePrimitiveIteratorOfDouble repeat(double value,
 long repeatCount)

Create a CloseablePrimitiveIteratorOfDouble that repeats value, repeatCount times. The result does not need to be closed.

Parameters:

value - The value to repeat

repeatCount - The number of repetitions

Returns:

A CloseablePrimitiveIteratorOfDouble that repeats value, repeatCount times

concat

static CloseablePrimitiveIteratorOfDouble concat(@NotNull
 @NotNull CloseablePrimitiveIteratorOfDouble... subIterators)

Create a CloseablePrimitiveIteratorOfDouble that concatenates an array of non-null subIterators. The result only needs to be closed if any of the subIterators require it.

Parameters:

subIterators - The iterators to concatenate, none of which should be null. If directly passing an array, ensure that this iterator has full ownership.

Returns:

A CloseablePrimitiveIteratorOfDouble concatenating all elements from subIterators

maybeConcat

static CloseablePrimitiveIteratorOfDouble maybeConcat(@Nullable
 @Nullable CloseablePrimitiveIteratorOfDouble first,
 @Nullable
 @Nullable CloseablePrimitiveIteratorOfDouble second,
 @Nullable
 @Nullable CloseablePrimitiveIteratorOfDouble third)

Return a CloseablePrimitiveIteratorOfDouble that concatenates the contents of any non-null CloseablePrimitiveIteratorOfDouble found amongst first, second, and third.

Parameters:

first - The first iterator to consider concatenating

second - The second iterator to consider concatenating

third - The third iterator to consider concatenating

Returns:

A CloseablePrimitiveIteratorOfDouble that concatenates all elements as specified
