Method Details

getLookupAttributes

Entry[] getLookupAttributes()
                     throws RemoteException

Get the current attribute sets for the service.

Returns:

the current attribute sets for the service

Throws:

RemoteException

addLookupAttributes

void addLookupAttributes(Entry[] attrSets)
                  throws RemoteException

Add attribute sets for the service. The resulting set will be used for all future joins. The attribute sets are also added to all currently-joined lookup services.

Parameters:

attrSets - the attribute sets to add

Throws:

RemoteException

modifyLookupAttributes

void modifyLookupAttributes(Entry[] attrSetTemplates,
 Entry[] attrSets)
                     throws RemoteException

Modify the current attribute sets, using the same semantics as ServiceRegistration.modifyAttributes. The resulting set will be used for all future joins. The same modifications are also made to all currently-joined lookup services.

Parameters:

attrSetTemplates - the templates for matching attribute sets

attrSets - the modifications to make to matching sets

Throws:

RemoteException

• ServiceRegistration.modifyAttributes(Entry[], Entry[])

getLookupGroups

String[] getLookupGroups()
                  throws RemoteException

Get the list of groups to join. An empty array means the service joins no groups (as opposed to "all" groups).

Returns:

an array of groups to join. An empty array means the service joins no groups (as opposed to "all" groups).

Throws:

RemoteException

See Also:

• setLookupGroups(String[])

addLookupGroups

void addLookupGroups(String[] groups)
              throws RemoteException

Add new groups to the set to join. Lookup services in the new groups will be discovered and joined.

Parameters:

groups - groups to join

Throws:

RemoteException

See Also:

• removeLookupGroups(String[])

removeLookupGroups

void removeLookupGroups(String[] groups)
                 throws RemoteException

Remove groups from the set to join. Leases are cancelled at lookup services that are not members of any of the remaining groups.

Parameters:

groups - groups to leave

Throws:

RemoteException

See Also:

• addLookupGroups(String[])

setLookupGroups

void setLookupGroups(String[] groups)
              throws RemoteException

Replace the list of groups to join with a new list. Leases are cancelled at lookup services that are not members of any of the new groups. Lookup services in the new groups will be discovered and joined.

Parameters:

groups - groups to join

Throws:

RemoteException

See Also:

• getLookupGroups()

getLookupLocators

LookupLocator[] getLookupLocators()
                           throws RemoteException

Get the list of locators of specific lookup services to join.

Returns:

the list of locators of specific lookup services to join

Throws:

RemoteException

See Also:

• setLookupLocators(LookupLocator[])

addLookupLocators

void addLookupLocators(LookupLocator[] locators)
                throws RemoteException

Add locators for specific new lookup services to join. The new lookup services will be discovered and joined.

Parameters:

locators - locators of specific lookup services to join

Throws:

RemoteException

See Also:

• removeLookupLocators(LookupLocator[])

removeLookupLocators

void removeLookupLocators(LookupLocator[] locators)
                   throws RemoteException

Remove locators for specific lookup services from the set to join. Any leases held at the lookup services are cancelled.

Parameters:

locators - locators of specific lookup services to leave

Throws:

RemoteException

See Also:

• addLookupLocators(LookupLocator[])

setLookupLocators

void setLookupLocators(LookupLocator[] locators)
                throws RemoteException

Replace the list of locators of specific lookup services to join with a new list. Leases are cancelled at lookup services that were in the old list but are not in the new list. Any new lookup services will be discovered and joined.

Parameters:

locators - locators of specific lookup services to join

Throws:

RemoteException
