getRecoverableTargets

public List<SpaceURL> getRecoverableTargets(String clusterName,
 String myMemberName,
 List<String> excludeTargets)

Finds all the recovery targets in cluster. If jini URLs are used, the first target will always be multicast url. only if it fails the unicast and rmi URLs will be used.

Parameters:

clusterName - the cluster to recover in.

myMemberName - the member of the cluster that needs to be recovered.

excludeTargets - targets that should be excluded from recovery

Returns:

a list of recoverable members SpaceURLs. returns empty list if recovery is disabled.
