handlesNameSubdomains

public boolean handlesNameSubdomains()

Description copied from interface: VHostListener

Indicates whether the component can handle packets to 'name' subdomain. Name subdomain is an artificial domain created from the component name and the domain name. The best example would be a 'MUC' component or a 'PubSub' component.
