getNewMembership

public java.util.List<Address> getNewMembership(java.util.Collection<Address> current_members,
                                       java.util.Collection<Address> joiners,
                                       java.util.Collection<Address> leavers,
                                       java.util.Collection<Address> suspects)

Takes the existing membership list and removes suspected and left members, then adds new members to the end of the list

指定者:

getNewMembership 在接口中 MembershipChangePolicy

参数:

current_members - The list of current members. Guaranteed to be non-null (but may be empty)

joiners - The joining members. Guaranteed to be non-null (but may be empty)

leavers - Members that are leaving. Guaranteed to be non-null (but may be empty)

suspects - Members which are suspected. Guaranteed to be non-null (but may be empty)

返回:

The new membership. Needs to be non-null and cannot contain duplicates

getNewMembershipOld

public static java.util.List<Address> getNewMembershipOld(java.util.Collection<java.util.Collection<Address>> subviews)

Old default implementation for a merge. Adds all members into a list, sorts the list and returns it

参数:

subviews - A list of membership lists, e.g. [{A,B,C}, {M,N,O,P}, {X,Y,Z}]. This is a merge between 3 subviews. Guaranteed to be non-null (but may be empty)

返回:

The new membership. Needs to be non-null and cannot contain duplicates

getNewMembership

public java.util.List<Address> getNewMembership(java.util.Collection<java.util.Collection<Address>> subviews)

Default implementation for a merge. Picks the new coordinator among the coordinators of the old subviews by getting all coords, sorting them and picking the first. Then the coord is adde to the new list, and all subviews are subsequently added.

Tries to minimize coordinatorship moving around between different members

指定者:

getNewMembership 在接口中 MembershipChangePolicy

参数:

subviews - A list of membership lists, e.g. [{A,B,C}, {M,N,O,P}, {X,Y,Z}]. This is a merge between 3 subviews. Guaranteed to be non-null (but may be empty)

返回:

The new membership. Needs to be non-null and cannot contain duplicates
