Method Detail

setDiscoveryListener

public void setDiscoveryListener(DiscoveryListener listener)

Description copied from interface: DiscoveryAgent

Sets the discovery listener

Specified by:

setDiscoveryListener in interface DiscoveryAgent

registerService

public void registerService(String name)
                     throws IOException

Description copied from interface: DiscoveryAgent

register a service

Specified by:

registerService in interface DiscoveryAgent

Throws:

IOException

start

public void start()
           throws Exception

Specified by:

start in interface Service

Throws:

Exception

stop

public void stop()
          throws Exception

Specified by:

stop in interface Service

Throws:

Exception

getServices

public String[] getServices()

setServices

public void setServices(String services)

setServices

public void setServices(String[] services)

setServices

public void setServices(URI[] services)

serviceFailed

public void serviceFailed(DiscoveryEvent devent)
                   throws IOException

Description copied from interface: DiscoveryAgent

A process actively using a service may see it go down before the DiscoveryAgent notices the service's failure. That process can use this method to notify the DiscoveryAgent of the failure so that other listeners of this DiscoveryAgent can also be made aware of the failure.

Specified by:

serviceFailed in interface DiscoveryAgent

Throws:

IOException
