Class Resource

org.hawkular.accounts.api.model.BaseEntity

org.hawkular.accounts.api.model.Resource

All Implemented Interfaces:

Serializable

public class Resource
extends BaseEntity

Represents a resource that is meant to be protected. Each module is free to define their own rules for creating Resources or defining its context. Examples of Resources could be: alerts, metrics, inventory items, ... Each resource is either owner by an Persona or is a sub resource (ie: it has a parent Resource). At the end of the chain, there must be a valid owner. The parent of a Resource can be reset by first setting an owner and then setting the parent to null. Failure to set an owner before resetting the parent will lead to IllegalStateException. Similarly, attempting to set the Owner to null without a valid parent first will lead to .IllegalStateException.
