Base server-side implementation of a lookup service, subclassed by TransientRegistrarImpl and PersistentRegistrarImpl. Multiple client-side proxy classes are used, for the ServiceRegistrar interface as well as for leases and administration; their methods transform the parameters and then make corresponding calls on the Registrar interface implemented on the server side.

Constructor Detail

GigaRegistrar

public GigaRegistrar(String[] configArgs,
                     LifeCycle lifeCycle)
              throws Exception

Constructs RegistrarImpl based on a configuration obtained using the provided string arguments. If activationID is non-null, the created RegistrarImpl runs as activatable; if persistent is true, it persists/recovers its state to/from disk. A RegistrarImpl instance cannot be constructed as both activatable and non-persistent. If lifeCycle is non-null, its unregister method is invoked during shutdown.

Throws:

Exception

Description copied from interface: DiscoveryAdmin

Adds the given set of names to the set whose elements are the names of the groups in which the lookup service is currently a member. Elements in the input set that duplicate names of groups in which the lookup service is already a member will be ignored. If the empty array (NO_GROUPS) is input, this method takes no action.

Specified by:

addMemberGroups in interface DiscoveryAdmin

Parameters:

groups - String array consisting of the names of the new, additional groups in which the lookup service is to be a member.

Throws:

NoSuchObjectException

removeMemberGroups

public void removeMemberGroups(String[] groups)
                        throws NoSuchObjectException

Description copied from interface: DiscoveryAdmin

Deletes the elements of the given set of names from the set whose elements are the names of the groups in which the lookup service is currently a member. Any element in the input set that is not a name of a group in which the lookup service is currently a member will be ignored. If the empty array (NO_GROUPS) is input, this method takes no action.

Specified by:

removeMemberGroups in interface DiscoveryAdmin

Parameters:

groups - String array consisting of the names to remove from the set whose elements are the names of the groups in which the lookup service is currently a member.

Throws:

NoSuchObjectException

getMemberGroups

public String[] getMemberGroups()
                         throws NoSuchObjectException

Description copied from interface: DiscoveryAdmin

Returns an array consisting of the names of the groups in which the lookup service is a member. If the lookup service currently belongs to no groups, this method will return the empty array.

Specified by:

getMemberGroups in interface DiscoveryAdmin

Returns:

String array consisting of the names of the groups in which the lookup service is a member

Throws:

NoSuchObjectException

setMemberGroups

public void setMemberGroups(String[] groups)
                     throws NoSuchObjectException

Description copied from interface: DiscoveryAdmin

Replaces the set whose elements are the names of the groups in which the lookup service is currently a member with the given set of group names. Elements in the input set that duplicate other elements in the input set will be ignored. If the empty array (NO_GROUPS) is input, then the lookup service will be a member of no groups.

Specified by:

setMemberGroups in interface DiscoveryAdmin

Parameters:

groups - String array consisting of the names of the new groups in which the lookup service is to be a member.

Throws:

NoSuchObjectException

getUnicastPort

public int getUnicastPort()
                   throws NoSuchObjectException

Description copied from interface: DiscoveryAdmin

Returns the port number on which the lookup service listens for unicast discovery queries.

Specified by:

getUnicastPort in interface DiscoveryAdmin

Returns:

an int representing the port number on which the lookup service listens for unicast discovery queries.

Throws:

NoSuchObjectException

setUnicastPort

public void setUnicastPort(int port)
                    throws IOException

Description copied from interface: DiscoveryAdmin

Changes the number of the port on which the lookup service is currently listening for unicast discovery queries to the given port number. If a value of zero is input, then the lookup service will first try to listen on the standard unicast discovery port, but if that fails, the lookup service will listen on an arbitrary port.

Specified by:

setUnicastPort in interface DiscoveryAdmin

Parameters:

port - int representing the new port number on which the lookup service should listen for unicast discovery queries.

Throws:

IOException - because an invocation of this method will result in the re-initiation of the unicast discovery process, which can throw an IOException when socket allocation occurs.

RemoteException - typically, this exception occurs when there is a communication failure between the client and the server.

destroy

public void destroy()
             throws RemoteException

Description copied from interface: DestroyAdmin

Destroy the service, if possible, including its persistent storage. This method should (in effect) spawn a separate thread to do the actual work asynchronously, and make a reasonable attempt to let this remote call return successfully. As such, a successful return from this method does not mean that the service has been destroyed. Although the service should make a reasonable attempt to let this remote call return successfully, the service must not wait indefinitely for other (in-progress and subsequent) remote calls to finish before proceeding to destroy itself. Once this method has been called, the service can, but need not, reject all other (in-progress and subsequent) remote calls to the service.

destroy in interface DestroyAdmin
