Field Details

EMPTY

static final ValueIteratorOfDouble EMPTY

A re-usable, immutable ValueIteratorOfDouble with no elements.

Method Details

next

@FinalDefault
default Double next()

Specified by:

next in interface Iterator<Double>

Specified by:

next in interface PrimitiveIterator.OfDouble

forEachRemaining

@FinalDefault
default void forEachRemaining(@NotNull
 @NotNull Consumer<? super Double> action)

Specified by:

forEachRemaining in interface Iterator<Double>

Specified by:

forEachRemaining in interface PrimitiveIterator.OfDouble

doubleStream

@FinalDefault
default DoubleStream doubleStream()

Create an unboxed DoubleStream over the remaining elements of this ValueIteratorOfDouble. The result must be closed in order to ensure resources are released. A try-with-resources block is strongly encouraged.

Specified by:

doubleStream in interface CloseablePrimitiveIteratorOfDouble

Returns:

An unboxed DoubleStream over the remaining contents of this iterator. Must be closed.

stream

@FinalDefault
default Stream<Double> stream()

Create a boxed Stream over the remaining elements of this ValueIteratorOfDouble. The result must be closed in order to ensure resources are released. A try-with-resources block is strongly encouraged.

Specified by:

stream in interface CloseableIterator<Double>

Specified by:

stream in interface ValueIterator<Double>

Returns:

A boxed Stream over the remaining contents of this iterator. Must be closed.

empty

static ValueIteratorOfDouble empty()

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

Returns:

A ValueIteratorOfDouble with no elements

of

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

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

Parameters:

values - The elements to iterate

Returns:

A ValueIteratorOfDouble of values

wrapWithNulls

static ValueIteratorOfDouble wrapWithNulls(@Nullable
 @Nullable ValueIteratorOfDouble iterator,
 long prefixNulls,
 long postfixNulls)

Wraps a ValueIteratorOfDouble with set number of prefix nulls, postfix nulls, or both. The result must be closed.

Parameters:

iterator - The ValueIteratorOfDouble to wrap

prefixNulls - The number of nulls to add to the beginning of the iterator

postfixNulls - The number of nulls to add to the end of the iterator

Returns:

A ValueIteratorOfDouble with the specified number of prefix and postfix nulls
