Send this message to the local
Replicator
to update a data value for the givenkey
. TheReplicator
will reply with one of the UpdateResponse messages.Note that the companion object provides
apply
functions for convenient construction of this message.The current data value for the
key
is passed as parameter to themodify
function. It isNone
if there is no value for thekey
, and otherwiseSome(data)
. The function is supposed to return the new value of the data, which will then be replicated according to the givenwriteConsistency
.The
modify
function is called by theReplicator
actor and must therefore be a pure function that only uses the data parameter and stable fields from enclosing scope. It must for example not accesssender()
reference of an enclosing actor.
