Interface DiscoveryAdmin

public abstract interface DiscoveryAdmin

Methods for controlling which groups a lookup service is a member of, and for controlling which TCP port a lookup service uses for its lookup locator. Lookup services that implement the Administrable interface should return an admin object that implements this interface.

Method Summary

void	addMemberGroups(java.lang.String[] groups) Add new groups for the lookup service to be a member of.
java.lang.String[]	getMemberGroups() Get the list of groups that the lookup service is a member of.
int	getUnicastPort() Get the port number on which the lookup service listens for unicast discovery queries.
void	removeMemberGroups(java.lang.String[] groups) Remove groups from list that the lookup service is a member of.
void	setMemberGroups(java.lang.String[] groups) Replace the list of groups to be a member of with a new list.
void	setUnicastPort(int port) Set the port number on which the lookup service listens for unicast discovery queries.

Method Detail

getMemberGroups

public java.lang.String[] getMemberGroups()
                                   throws java.rmi.RemoteException

Get the list of groups that the lookup service is a member of. An empty array means the lookup service is a member of no groups (as opposed to "all" groups).

Returns:

a String array of groups that the lookup service is a member of.

Throws:

java.rmi.RemoteException -

addMemberGroups

public void addMemberGroups(java.lang.String[] groups)
                     throws java.rmi.RemoteException

Add new groups for the lookup service to be a member of.

Parameters:

groups - groups to be a member of

Throws:

java.rmi.RemoteException -

removeMemberGroups

public void removeMemberGroups(java.lang.String[] groups)
                        throws java.rmi.RemoteException

Remove groups from list that the lookup service is a member of.

Parameters:

groups - groups to stop being a member of

Throws:

java.rmi.RemoteException -

setMemberGroups

public void setMemberGroups(java.lang.String[] groups)
                     throws java.rmi.RemoteException

Replace the list of groups to be a member of with a new list.

Parameters:

groups - groups to be a member of

Throws:

java.rmi.RemoteException -

getUnicastPort

public int getUnicastPort()
                   throws java.rmi.RemoteException

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

Returns:

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

Throws:

java.rmi.RemoteException -

setUnicastPort

public void setUnicastPort(int port)
                    throws java.io.IOException,
                           java.rmi.RemoteException

Set the port number on which the lookup service listens for unicast discovery queries. A port of zero means the lookup service should first try to listen on the standard unicast discovery port, but if that fails, then it should listen on an arbitrary port.

Parameters:

port - the port number

Throws:

java.io.IOException -

java.rmi.RemoteException -
