      • intIterator

        public IntIterator intIterator()
        Description copied from interface: CharCollection
        Returns a widened primitive iterator on the elements of this collection.

        This method is provided for the purpose of APIs that expect only the JDK's primitive iterators, of which there are only int, long, and double.

        WARNING: This is not the same as converting the source to a sequence of code points. This returned instance literally performs (int)(charValue) casts. Surrogate pairs will be left as separate elements instead of combined into a single element with the code point it represents. See Character for more discussion on code points, char values, and surrogate pairs.

        Returns:
        a widened primitive iterator on the elements of this collection.
      • intSpliterator

        public IntSpliterator intSpliterator()

        Returns widened primitive spliterator on the elements of this collection.
