CPSubsystem
IAtomicLong
instance created on the CP
subsystem. Hazelcast's IAtomicLong
is a distributed version of
java.util.concurrent.atomic.AtomicLong. If no group name is
given within the "name" parameter, then the IAtomicLong
instance
will be created on the DEFAULT CP group. If a group name is given, like
.getAtomicLong("myLong@group1")
, the given group will be
initialized first, if not initialized already, and then the
IAtomicLong
instance will be created on this group. Returned
IAtomicLong
instance offers linearizability and behaves as a CP
register. When a network partition occurs, proxies that exist on the
minority side of its CP group lose availability.getAtomicLong

CPSubsystem
IAtomicReference
instance created on
the CP subsystem. Hazelcast's IAtomicReference
is a distributed
version of java.util.concurrent.atomic.AtomicLong. If no group
name is given within the "name" parameter, then
the IAtomicReference
instance will be created on the DEFAULT CP
group. If a group name is given, like
.getAtomicReference("myRef@group1")
, the given group will be
initialized first, if not initialized already, and then the
IAtomicReference
instance will be created on this group.

instance will be created on the DEFAULT CP

public CPMember getLocalCPMember()
CPSubsystem
This field is initialized when the local Hazelcast member is one of
the first CPSubsystemConfig.getCPMemberCount()
members
in the cluster and the CP subsystem discovery process is completed.
This method fails with HazelcastException
if the CP subsystem
is not enabled.
