Method Details

next

@FinalDefault
default Character next()

Specified by:

next in interface CloseablePrimitiveIteratorOfChar

Specified by:

next in interface Iterator<Character>

forEachRemaining

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

Specified by:

forEachRemaining in interface CloseablePrimitiveIteratorOfChar

Specified by:

forEachRemaining in interface Iterator<Character>

streamAsInt

@FinalDefault
default IntStream streamAsInt(@NotNull
 @NotNull CharToIntFunction adapter)

Create a IntStream over the remaining elements of this ChunkedCharacterColumnIterator by applying adapter to each element. The result must be closed in order to ensure resources are released. A try-with-resources block is strongly encouraged.

Specified by:

streamAsInt in interface CloseablePrimitiveIteratorOfChar

Returns:

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

streamAsInt

@FinalDefault
default IntStream streamAsInt()

Create an unboxed IntStream over the remaining elements of this ChunkedCharacterColumnIterator by casting each element to int with the appropriate adjustment of NULL_CHAR to NULL_INT. The result must be closed in order to ensure resources are released. A try-with-resources block is strongly encouraged.

Specified by:

streamAsInt in interface CloseablePrimitiveIteratorOfChar

Returns:

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

stream

@FinalDefault
default Stream<Character> stream()

Create a boxed Stream over the remaining elements of this CharColumnIterator. 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<Character>

Returns:

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