All Implemented Interfaces:

CollectionResource, ResourceIdentifier

public abstract class AbstractCollectionResource
extends Object
implements CollectionResource

A base (partial) implementation of CollectionResource, implementing common features (to reduce repeated code) Typically used by the non-SNMP collectors (SNMP has it's own set of classes for this). Provides a basic group of ag Provides support, via addAttribute, getGroup, and getGroups, for basic "groups" of attributes. Also provides a sample "visit" implementation based on those groups, although this may well be overridden by subclasses
