      • wouldIBeCoordinator

        protected boolean wouldIBeCoordinator​(java.util.Collection<Address> leaving_mbrs)
        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.
