Chris@0 15 * Specifies whether an object should be cascaded.
Chris@0 16 *
Chris@0 17 * Cascading is relevant for any node type but class nodes. If such a node
Chris@0 18 * contains an object of value, and if cascading is enabled, then the node
Chris@0 19 * traverser will try to find class metadata for that object and validate the
Chris@0 20 * object against that metadata.
Chris@0 21 *
Chris@0 22 * If no metadata is found for a cascaded object, and if that object implements
Chris@0 23 * {@link \Traversable}, the node traverser will iterate over the object and
Chris@0 24 * cascade each object or collection contained within, unless iteration is
Chris@0 25 * prohibited by the specified {@link TraversalStrategy}.
Chris@0 26 *
Chris@0 27 * Although the constants currently represent a boolean switch, they are
Chris@0 28 * implemented as bit mask in order to allow future extensions.
