DatabaseWriter |
org.sdm.spa.DatabaseWriter |
This actor reads a SQL update string from its input and execute the
update on the database specified by the databaseURL parameter.
FIXME: I am convinced that we should pass the db connection around if
we need more than one db actors to connect to the same database. (the
alternative is to combine DatabaseReader and DatabaseWriter to one class.
but this makes the actor interface a little nasty...
