Method Detail

equals

public static boolean equals(PrimitiveIterator.OfInt a,
                             PrimitiveIterator.OfInt b)

from

public static PrimitiveIterator.OfInt from(BitSet bitSet)

filter

public static PrimitiveIterator.OfInt filter(PrimitiveIterator.OfInt it,
                                             IntPredicate f)

Parameters:

it - an iterator

f - a predicate

Returns:

an iterator which only yields values that satisfy the predicate

map

public static PrimitiveIterator.OfInt map(PrimitiveIterator.OfInt it,
                                          IntUnaryOperator f)

Parameters:

it - an iterator

f - a function which transforms values

Returns:

an iterator which yields the transformed values

flatMap

public static <U> PrimitiveIterator.OfInt flatMap(Iterator<U> it,
                                                  Function<U,PrimitiveIterator.OfInt> f)

Parameters:

it - an iterator

f - a function which transforms values into iterators

Returns:

an iterator which yields the concatenation of the iterators

range

public static PrimitiveIterator.OfInt range(long min,
                                            long max,
                                            LongToIntFunction f)

Parameters:

min - an inclusive start of the range

max - an exclusive end of the range

f - a function which transforms a number in the range into a value

Returns:

an iterator which yields the values returned by f

range

public static PrimitiveIterator.OfInt range(long max,
                                            LongToIntFunction f)

Represents a range implicitly starting at 0.

Parameters:

max - an exclusive end of the range.

f - a function which transforms a number in the range into a value.

Returns:

an iterator which yields the values returned by f

toStream

public static IntStream toStream(PrimitiveIterator.OfInt it,
                                 long estimatedSize)
