Field Details

EMPTY

static final ValueIteratorOfFloat EMPTY

A re-usable, immutable ValueIteratorOfFloat with no elements.

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()

Create an unboxed DoubleStream over the remaining elements of this ValueIteratorOfFloat 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.

streamAsDouble

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

Create an DoubleStream over the remaining elements of this ValueIteratorOfFloat 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:

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

empty

static ValueIteratorOfFloat empty()

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

Returns:

A ValueIteratorOfFloat with no elements

of

static ValueIteratorOfFloat of(@NotNull
 @org.jetbrains.annotations.NotNull float... values)

Create a ValueIteratorOfFloat over an array of float. The result does not need to be closed.

Parameters:

values - The elements to iterate

Returns:

A ValueIteratorOfFloat of values

wrapWithNulls

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

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

Parameters:

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