Method Detail

getSocketInfo

public List getSocketInfo(IOR ior,
                          List previous)

Description copied from interface: IORToSocketInfo

Used to extract socket address information from an IOR.

Specified by:

getSocketInfo in interface IORToSocketInfo

Parameters:

ior - The ior from which the socket info is extracted.

previous - The previous list, which may be reused if not null.

Returns:

a list of SocketInfo.

reset

public void reset(ContactInfo primary)

Specified by:

reset in interface IIOPPrimaryToContactInfo

Parameters:

primary - - clear any state relating to primary.

hasNext

public boolean hasNext(ContactInfo primary,
                       ContactInfo previous,
                       List contactInfos)

Specified by:

hasNext in interface IIOPPrimaryToContactInfo

Parameters:

primary - - the key.

previous - - if null return true. Otherwise, find previous in contactInfos and if another ContactInfo follows it in the list then return true. Otherwise false.

contactInfos - - the list of replicas associated with the primary.

next

public ContactInfo next(ContactInfo primary,
                        ContactInfo previous,
                        List contactInfos)

Specified by:

next in interface IIOPPrimaryToContactInfo

Parameters:

primary - - the key.

previous - - if null then map primary to failover. If failover is empty then map primary to first ContactInfo in contactInfos and mapped entry. If failover is non-empty then return failover. If previous is non-null that indicates that the previous failed. Therefore, find previous in contactInfos. Map the ContactInfo following previous to primary and return that ContactInfo.

getInitialClusterInstanceInfo

public List<ClusterInstanceInfo> getInitialClusterInstanceInfo(ORB orb,
                                                               List<String> endpoints)

addObserver

public boolean addObserver(GroupInfoServiceObserver x)

Description copied from interface: GroupInfoService

Adds an observer that will receive a membershipChange invocation whenever the cluster membership changes. The membershipChange invocation tells the observer to call getClusterInstanceInfo to get info.

Specified by:

addObserver in interface GroupInfoService

Returns:

true if the given observer is added. False otherwise.

notifyObservers

public void notifyObservers()

Description copied from interface: GroupInfoService

Causes the membershipChange method to be called on each registered observer.

Specified by:

notifyObservers in interface GroupInfoService

getClusterInstanceInfo

public List<ClusterInstanceInfo> getClusterInstanceInfo(String[] adapterName)

Description copied from interface: GroupInfoService

This is a separate call (rather than info being passed in membershipChange) so we can identifier the adapter. The adapter identification is used in testing.

Specified by:

getClusterInstanceInfo in interface GroupInfoService

getClusterInstanceInfo

public List<ClusterInstanceInfo> getClusterInstanceInfo(String[] adapterName,
                                                        List<String> endpoints)

Description copied from interface: GroupInfoService

This is a separate call (rather than info being passed in membershipChange) so we can identifier the adapter. The adapter identification is used in testing.

Specified by:

getClusterInstanceInfo in interface GroupInfoService

shouldAddAddressesToNonReferenceFactory

public boolean shouldAddAddressesToNonReferenceFactory(String[] x)

Description copied from interface: GroupInfoService

This method only used during testing.

Specified by:

shouldAddAddressesToNonReferenceFactory in interface GroupInfoService

shouldAddMembershipLabel

public boolean shouldAddMembershipLabel(String[] adapterName)

Description copied from interface: GroupInfoService

This method only used during testing.

Specified by:

shouldAddMembershipLabel in interface GroupInfoService
