## Interface ClientAtomicLong

- All Superinterfaces:
    AutoCloseable, Closeable

      public interface ClientAtomicLong
      extends Closeable

  Distributed atomic long API.

  # Functionality

  Distributed atomic long includes the following main functionality:
  - Method `get()` gets current value of atomic long.
  - Various `get..(..)` methods get current value of atomic long and increase or decrease value of atomic long.
  - Method `addAndGet(long l)` sums `l` with current value of atomic long and returns result.
  - Method `incrementAndGet()` increases value of atomic long and returns result.
  - Method `decrementAndGet()` decreases value of atomic long and returns result.
  - Method `getAndSet(long l)` gets current value of atomic long and sets `l` as value of atomic long.
  - Method `name()` gets name of atomic long.

  # Creating Distributed Atomic Long

  Instance of distributed atomic long can be created by calling the following method:
  - `IgniteClient.atomicLong(String, long, boolean)`
  See Also:
    `IgniteClient.atomicLong(String, long, boolean)`
