class CascadingStrategy in Zircon Profile 8

Specifies whether an object should be cascaded.

Cascading is relevant for any node type but class nodes. If such a node contains an object of value, and if cascading is enabled, then the node traverser will try to find class metadata for that object and validate the object against that metadata.

If no metadata is found for a cascaded object, and if that object implements {@link \Traversable}, the node traverser will iterate over the object and cascade each object or collection contained within, unless iteration is prohibited by the specified {@link TraversalStrategy}.

Although the constants currently represent a boolean switch, they are implemented as bit mask in order to allow future extensions.
