Constructor Detail
ParticipantGmsImpl
public ParticipantGmsImpl(GMS g)(Code)




Method Detail
handleJoinResponse
public void handleJoinResponse(JoinRsp join_rsp)(Code)
In case we get a different JOIN_RSP from a previous JOIN_REQ sent by us (as a client), we simply apply the new view if it is greater than ours
Parameters:
  join_rsp -



handleLeaveResponse
public void handleLeaveResponse()(Code)



handleMembershipChange
public void handleMembershipChange(Collection newMembers, Collection leavingMembers, Collection suspectedMembers)(Code)



handleMergeRequest
public void handleMergeRequest(Address sender, ViewId merge_id)(Code)



handleViewChange
public void handleViewChange(View new_view, Digest digest)(Code)
If we are leaving, we have to wait for the view change (last msg in the current view) that excludes us before we can leave.
Parameters:
  new_view - The view to be installed
Parameters:
  digest - If view is a MergeView, digest contains the seqno digest of all members and has tobe set by GMS



init
public void init() throws Exception(Code)



join
public void join(Address mbr)(Code)



leave
public void leave(Address mbr)(Code)
Loop: determine coord. If coord is me --> handleLeave(). Else send handleLeave() to coord until success



sendLeaveMessage
void sendLeaveMessage(Address coord, Address mbr)(Code)



suspect
public void suspect(Address mbr)(Code)



unsuspect
public void unsuspect(Address mbr)(Code)
Removes previously suspected member from list of currently suspected members



wouldIBeCoordinator
boolean wouldIBeCoordinator()(Code)
Determines whether this member is the new coordinator given a list of suspected members. This is computed as follows: the list of currently suspected members (suspected_mbrs) is removed from the current membership. If the first member of the resulting list is equals to the local_addr, then it is true, otherwise false. Example: own address is B, current membership is {A, B, C, D}, suspected members are {A, D}. The resulting list is {B, C}. The first member of {B, C} is B, which is equal to the local_addr. Therefore, true is returned.
