------------------------------------

             Summary: Refactor ATOMIC_INCREMENT and ATOMIC_DECREMENT REST commands to use
entry processor
                 Key: IGNITE-881
                 URL: https://issues.apache.org/jira/browse/IGNITE-881
             Project: Ignite
          Issue Type: Task
          Components: newbie
            Reporter: Yakov Zhdanov


Currently, these commands alter the state of CacheAtomicLong, but they will be more flexible
if they atomically change cache key-value mapping.

Consider the following:
# Move handling logic to GridCacheCommandHandler
# Whenever command is received handling node should call {{org.apache.ignite.IgniteCache#invoke(K,
org.apache.ignite.cache.CacheEntryProcessor<K,V,T>, java.lang.Object...)}} to properly
change the value (depending on the argument) and return result
# If value is not a Number, error should be returned to the caller.
