atomic

public org.nustaq.kontraktor.IPromise atomic(String key,
                                             RLFunction<Record,Object> action)

Description copied from interface: RealLiveTable

apply the function to the record with given key and return the result inside a promise changes to the record inside the function are applied to the real record and a change message is generated. In case the function returns a changemessage (add,putRecord,remove ..), the change message is applied to the original record and broadcasted. Else the result of the action function is passed to the remote callee

Specified by:

atomic in interface RealLiveTable

Returns:

the result of function.

Specified by:

atomicUpdate in interface RealLiveTable

Parameters:

filter - - selects records

action - - function, the function might modify the record using putField. If false is returned, the record is deleted
