public Spliterator<E> spliterator() {
return new Spliterators.AbstractSpliterator<E>(
size(), SPLITERATOR_CHARACTERISTICS | Spliterator.SIZED) {

return true;
} else {
return false;
}

示例2: iterate
import java.util.Spliterators; //导入方法依赖的package包/类
/**
* Returns an infinite sequential ordered {@code Stream} produced by iterative
* application of a function {@code f} to an initial element {@code seed},
* producing a {@code Stream} consisting of {@code seed}, {@code f(seed)},
* {@code f(f(seed))}, etc.
*
* <p>The first element (position {@code 0}) in the {@code Stream} will be
* the provided {@code seed}. For {@code n > 0}, the element at position
* {@code n}, will be the result of applying the function {@code f} to the
* element at position {@code n - 1}.
*
* <p>The action of applying {@code f} for one element
* <a href="../concurrent/package-summary.html#MemoryVisibility"><i>happens-before</i></a>
* the action of applying {@code f} for subsequent elements. For any given
* element the action may be performed in whatever thread the library
* chooses.
*
* @param <T> the type of stream elements
* @param seed the initial element
* @param f a function to be applied to the previous element to produce
* a new element
* @return a new sequential {@code Stream}
