atomicQuery

public org.nustaq.kontraktor.IPromise atomicQuery(int senderId, java.lang.String key, RLFunction<Record,java.lang.Object> action)

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 the change is broadcasted

Parameters:

key -

action -

Returns:

the result of function.
