Field Detail

DEFAULT

static final ParallelStrategy DEFAULT

A Parallel Strategy that is Java's default Iterator to Spliterator converter. It favors relatively large sets (in the ten thousands or more) with low computational overhead.

COMPUTE_INTENSITY_MEDIUM

static final ParallelStrategy COMPUTE_INTENSITY_MEDIUM

A Parallel Strategy that favors relatively small to medium sets with medium computational overhead.

COMPUTE_INTENSITY_HIGH

static final ParallelStrategy COMPUTE_INTENSITY_HIGH

A Parallel Strategy that favors relatively small to medium sets with high computational overhead.

COMPUTE_INTENSITY_EXTREME

static final ParallelStrategy COMPUTE_INTENSITY_EXTREME

A Parallel Strategy that favors small sets with extremely high computational overhead. The set will be split up in solitary elements that are executed separately in their own thread.

Method Detail

spliteratorUnknownSize

<T> Spliterator<T> spliteratorUnknownSize(Iterator<? extends T> iterator,
                                          int characteristics)
