* * Characteristic value signifying that the element source may be safely * concurrently modified (allowing additions, replacements, and/or removals) * by multiple threads without external synchronization.

* * Characteristic value signifying that, for each pair of * encountered elements {@code x, y}, {@code !x.equals(y)}.

* * Characteristic value signifying that the element source cannot be * structurally modified; that is, elements cannot be added, replaced, or * removed, so such changes cannot occur during traversal.

* * Characteristic value signifying that the source guarantees that * encountered elements will not be {@code null}.

* * Characteristic value signifying that an encounter order is defined for * elements.

* * Characteristic value signifying that the value returned from * {@code estimateSize()} prior to traversal or splitting represents a * finite size that, in the absence of structural source modification, * represents an exact count of the number of elements that would be * encountered by a complete traversal.

* * Characteristic value signifying that encounter order follows a defined * sort order.

* * Characteristic value signifying that all Spliterators resulting from * {@code trySplit()} will be both {@link #SpliteratorSIZED} and {@link #SUBSIZED}.

* * An object for traversing and partitioning elements of a source.
