Method Details

next

@FinalDefault
default Float next()

Specified by:

next in interface CloseablePrimitiveIteratorOfFloat

Specified by:

next in interface Iterator<Float>

forEachRemaining

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

Specified by:

forEachRemaining in interface CloseablePrimitiveIteratorOfFloat

Specified by:

forEachRemaining in interface Iterator<Float>

streamAsDouble

@FinalDefault
default DoubleStream streamAsDouble(@NotNull
 @NotNull FloatToDoubleFunction adapter)

Create a DoubleStream over the remaining elements of this ChunkedFloatColumnIterator 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:

streamAsDouble in interface CloseablePrimitiveIteratorOfFloat

Returns:

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

streamAsDouble

@FinalDefault
default DoubleStream streamAsDouble()

Create an unboxed DoubleStream over the remaining elements of this ChunkedFloatColumnIterator by casting each element to double with the appropriate adjustment of NULL_FLOAT to NULL_DOUBLE. The result must be closed in order to ensure resources are released. A try-with-resources block is strongly encouraged.

Specified by:

streamAsDouble in interface CloseablePrimitiveIteratorOfFloat

Returns:

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

stream

@FinalDefault
default Stream<Float> stream()

Create a boxed Stream over the remaining elements of this FloatColumnIterator. 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<Float>

Returns:

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