/**
|
|
* 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.
