Method Detail

atomic

org.nustaq.kontraktor.IPromise atomic(String key,
                                      RLFunction<Record,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 broadcasted

Parameters:

key -

action -

Returns:

the result of function.

atomicUpdate

void atomicUpdate(RLPredicate<Record> filter,
                  RLFunction<Record,Boolean> action)

mass update.

Parameters:

filter - - selects records

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