- * {@code Stream} by generating elements individually and adding them to the
- * {@code StreamBuilder} (without the copying overhead that comes from using
- * an {@code ArrayList} as a temporary buffer.)
- *
- * <p>A {@code StreamBuilder} has a lifecycle, where it starts in a building
- * phase, during which elements can be added, and then transitions to a built
- * phase, after which elements may not be added. The built phase begins
- * when the {@link #build()} method is called, which creates an ordered
- * {@code Stream} whose elements are the elements that were added to the stream
- * builder, in the order they were added.
- *
- * <p>Primitive specializations of {@code StreamBuilder} are provided
- * for {@link OfInt int}, {@link OfLong long}, and {@link OfDouble double}
- * values.
