Field Details

EMPTY

static final ValueIteratorOfInt EMPTY

A re-usable, immutable ValueIteratorOfInt with no elements.

Method Details

next

@FinalDefault
default Integer next()

Specified by:

next in interface Iterator<Integer>

Specified by:

next in interface PrimitiveIterator.OfInt

forEachRemaining

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

Specified by:

forEachRemaining in interface Iterator<Integer>

Specified by:

forEachRemaining in interface PrimitiveIterator.OfInt

intStream

@FinalDefault
default IntStream intStream()

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

Specified by:

intStream in interface CloseablePrimitiveIteratorOfInt

Returns:

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

stream

@FinalDefault
default Stream<Integer> stream()

Create a boxed Stream over the remaining elements of this DeephavenValueIteratorOfInt. 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<Integer>

Specified by:

stream in interface ValueIterator<Integer>

Returns:

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

empty

static ValueIteratorOfInt empty()

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

Returns:

A ValueIteratorOfInt with no elements

of

static ValueIteratorOfInt of(@NotNull
 @org.jetbrains.annotations.NotNull int... values)

Create a ValueIteratorOfInt over an array of int. The result does not need to be closed.

Parameters:

values - The elements to iterate

Returns:

A ValueIteratorOfInt of values

wrapWithNulls

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

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

Parameters:

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