Method Detail

getKind

public abstract ServiceUpEvent.EventKind getKind()

Service up events can be member up, composite up, or both. This method reports which this is. A member up means just a single member instance of the service is up. A composite up means that all member instances of the service are up and so the service itself is up. A single event can report both the last member up and the composite up. These may also come as separate events.

Returns:

the event kind.

getServiceName

public abstract java.lang.String getServiceName()

Returns:

the service name.

getDatabaseUniqueName

public abstract java.lang.String getDatabaseUniqueName()

Returns:

the database unique name.

getReason

public abstract ServiceUpEvent.Reason getReason()

Returns:

the reason for the service going up.

getCardinality

public abstract int getCardinality()

Returns:

the cardinality for the service going up.

getServiceMemberEvent

public abstract ServiceUpEvent.ServiceMemberEvent getServiceMemberEvent()

Return the service member subevent information if this is a service member event. Returns null if this kind is COMPOSITE. A service event can be either a member or composite event, or both.

Returns:

a ServiceMemberEvent or null.
