Class ServiceInfo

java.lang.Object

javax.jmdns.ServiceInfo

All Implemented Interfaces:

java.lang.Cloneable

Direct Known Subclasses:

ServiceInfoImpl

public abstract class ServiceInfo
extends java.lang.Object
implements java.lang.Cloneable

The fully qualified service name is build using up to 5 components with the following structure:

            <app>.<protocol>.<servicedomain>.<parentdomain>.

 <Instance>.<app>.<protocol>.<servicedomain>.<parentdomain>.

 <sub>._sub.<app>.<protocol>.<servicedomain>.<parentdomain>.
 

1. <servicedomain>.<parentdomain>: This is the domain scope of the service typically "local.", but this can also be something similar to "in-addr.arpa." or "ip6.arpa."
2. <protocol>: This is either "_tcp" or "_udp"
3. <app>: This define the application protocol. Typical example are "_http", "_ftp", etc.
4. <Instance>: This is the service name
5. <sub>: This is the subtype for the application protocol
