Method Detail

addMembershipListener

public String addMembershipListener(MembershipListener listener)

Description copied from interface: Cluster

Adds MembershipListener to listen for membership updates.

The addMembershipListener method returns a register-id. This id is needed to remove the MembershipListener using the Cluster.removeMembershipListener(String) method.

If the MembershipListener implements the InitialMembershipListener interface, it will also receive the InitialMembershipEvent.

There is no check for duplicate registrations, so if you register the listener twice, it will get events twice.

Specified by:

addMembershipListener in interface Cluster

Parameters:

listener - membership listener

Returns:

the registration id.

See Also:

Cluster.removeMembershipListener(String)

removeMembershipListener

public boolean removeMembershipListener(String registrationId)

Description copied from interface: Cluster

Removes the specified MembershipListener.

If the same MembershipListener is registered multiple times, it needs to be removed multiple times. This method can safely be called multiple times for the same registration-id; subsequent calls are ignored.

Specified by:

removeMembershipListener in interface Cluster

Parameters:

registrationId - the registrationId of MembershipListener to remove.

Returns:

true if the registration is removed, false otherwise.

Cluster.addMembershipListener(MembershipListener)

getMembers

public Set<Member> getMembers()

Description copied from interface: Cluster

Set of the current members in the cluster. The returned set is an immutable set; it can't be modified.

The returned set is backed by an ordered set. Every member in the cluster returns the 'members' in the same order. To obtain the oldest member (the master) in the cluster, you can retrieve the first item in the set using 'getMembers().iterator().next()'.

Specified by:

getMembers in interface Cluster

Returns:

current members in the cluster

getLocalMember

public Member getLocalMember()

Description copied from interface: Cluster

Returns this Hazelcast instance member.

Specified by:

getLocalMember in interface Cluster

Returns:

this Hazelcast instance member

getClusterTime

public long getClusterTime()

Description copied from interface: Cluster

Returns the cluster-wide time in milliseconds.

Cluster tries to keep a cluster-wide time which might be different than the member's own system time. Cluster-wide time is -almost- the same on all members of the cluster.

Specified by:

getClusterTime in interface Cluster

Returns:

cluster-wide time
