# FilteredResource

A filtered resource is a resource that supports filters (see the Jigsaw architectural overview if you're unfamiliar with this notion). By itself, a filtered resource doesn't define any new attributes, however, each of the filters attached to the resource maitains a shadow copy of the target resource attribute values. Hence, a filtered resource attribute value is looked up in the following fashion: first all its filters are queried for the looked-up attribute. If one of them defines the attribute, then this value is returned (this allows filters to shadow attribute values, based on the processing they do on the resource reply). Otherwise, the appropriate filtered resource attribute value is returned.

## Inherits
