AbstractServiceLoadBalancer

public AbstractServiceLoadBalancer()

Method Details

init

public void init(S service)

Called by the Service exactly once on this object as part of its initialization.

Specified by:

init in interface ServiceLoadBalancer<S extends Service, T extends ServiceLoad>

Parameters:

service - the containing Service

getLocalMember

protected Member getLocalMember()

Return the Member object representing the local cluster member.

Returns:

the Member object representing the local cluster member

isLocalMember

protected boolean isLocalMember(Member member)

Check whether the specified Member object represents the local member of the cluster.

Parameters:

member - the Member object in question

Returns:

true iff the Member object represents the local cluster member

getService

public S getService()

Obtain the containing Service.

Returns:

the containing Service
