Internal API.

Constructor.

Member Function Documentation

const Cluster & hazelcast::client::MembershipEvent::getCluster ( ) const

virtual

Returns the cluster of the event.

Returns

MembershipEvent::MembershipEventType hazelcast::client::MembershipEvent::getEventType ( ) const

virtual

Returns the membership event type; MembershipEvent::MEMBER_ADDED , MembershipEvent::MEMBER_REMOVED and MembershipEvent::MEMBER_ATTRIBUTE_CHANGED.

Returns

the membership event type

const Member & hazelcast::client::MembershipEvent::getMember ( ) const

virtual

Returns the removed or added member.

Returns

member which is removed/added

const std::vector< Member > hazelcast::client::MembershipEvent::getMembers ( ) const

virtual

Returns a consistent view of the the members exactly after this MembershipEvent has been processed.

So if a member is removed, the returned set will not include this member. And if a member is added it will include this member.

The problem with calling the Cluster::getMembers() is that the content could already have changed while processing this event so it becomes very difficult to write a deterministic algorithm since you can't get a deterministic view of the members. This method solves that problem.

The set is immutable and ordered. For more information see Cluster::getMembers().

Returns

the members at the moment after this event.
