Implements distributed atomic long.

https://curator.apache.org/curator-recipes/distributed-atomic-long.html

add! clj

(add! distributed-atomic-long delta)

Add delta to the current value. Return true on success, false otherwise.

current-value clj

(current-value distributed-atomic-long)

Return the current value of a DistributedAtomicLong

decrement! clj

(decrement! distributed-atomic-long)

Subtract 1 from the current value. Return true on success, false otherwise.

distributed-atomic-long clj

(distributed-atomic-long curator-framework counter-path retry-policy)

Create a distributed atomic long in optimistic mode.

Requires the following parameters:

• curator-framework: instance of Curator
• counter-path: path of the counter (as a string)
• retry-policy: a retry policy, see http://curator.apache.org/apidocs/index.html

After each operation you MUST first check succeeded() which returns true if the operation succeeded.

force-set! clj

(force-set! distributed-atomic-long value)

Forcibly sets the value of the counter without any guarantees of atomicity.

increment! clj

(increment! distributed-atomic-long)

Add 1 to the current value. Return true on success, false otherwise.

subtract! clj

(subtract! distributed-atomic-long delta)

Subtract delta from the current value. Return true on success, false otherwise.
