Field Details

EMPTY

static final ValueIteratorOfLong EMPTY

A re-usable, immutable ValueIteratorOfLong with no elements.

Method Details

next

@FinalDefault
default Long next()

Specified by:

next in interface Iterator<Long>

Specified by:

next in interface PrimitiveIterator.OfLong

forEachRemaining

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

Specified by:

forEachRemaining in interface Iterator<Long>

Specified by:

forEachRemaining in interface PrimitiveIterator.OfLong

longStream

@FinalDefault
default LongStream longStream()

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

Specified by:

longStream in interface CloseablePrimitiveIteratorOfLong

Returns:

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

stream

@FinalDefault
default Stream<Long> stream()

Create a boxed Stream over the remaining elements of this ValueIteratorOfLong. 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<Long>

Specified by:

stream in interface ValueIterator<Long>

Returns:

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

empty

static ValueIteratorOfLong empty()

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

Returns:

A ValueIteratorOfLong with no elements

of

static ValueIteratorOfLong of(@NotNull
 @org.jetbrains.annotations.NotNull long... values)

Create a ValueIteratorOfLong over an array of long. The result does not need to be closed.

Parameters:

values - The elements to iterate

Returns:

A ValueIteratorOfLong of values

wrapWithNulls

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

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

Parameters:

iterator - The ValueIteratorOfLong 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 ValueIteratorOfLong with the specified number of prefix and postfix nulls
