    • getAtomicLong

      @Nonnull public IAtomicLong getAtomicLong(@Nonnull String name)
      Description copied from interface: CPSubsystem
      Returns a proxy for an IAtomicLong instance created on 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.

      Each call of this method performs a commit to the METADATA CP group. Hence, callers should cache the returned proxy.

      Specified by:
      getAtomicLong in interface CPSubsystem
      Parameters:
      name - name of the IAtomicLong proxy
      Returns:
      IAtomicLong proxy for the given name

    • getAtomicReference

      @Nonnull public <E> IAtomicReference<E> getAtomicReference(@Nonnull String name)
      Description copied from interface: CPSubsystem
      Returns a proxy for an IAtomicReference instance created on CP Subsystem. Hazelcast's IAtomicReference is a distributed version of java.util.concurrent.atomic.AtomicReference. 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. Returned IAtomicReference 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.

      Each call of this method performs a commit to the METADATA CP group. Hence, callers should cache the returned proxy.
