Class ServiceTemplate

java.lang.Object
  |
  +--net.jini.core.lookup.ServiceTemplate

public class ServiceTemplate
extends java.lang.Object
implements java.io.Serializable

Items in the lookup service are matched using instance of this class. A service item (item) matches a service template (tmpl) if: item.serviceID equals tmpl.serviceID (or if tmpl.serviceID is null); and item.service is an instance of every type in tmpl.serviceTypes; and item.attributeSets contains at least one matching entry for each entry template in tmpl.attributeSetTemplates.

An entry matches an entry template if the class of the template is the same as, or a superclass of, the class of the entry, and every non-null field in the template equals the corresponding field of the entry. Every entry can be used to match more than one template. Note that in a service template, for serviceTypes and attributeSetTemplates, a null field is equivalent to an empty array; both represent a wildcard.
