Class ProcessStoreImpl

java.lang.Object

org.apache.ode.store.ProcessStoreImpl

All Implemented Interfaces:

ProcessStore

public class ProcessStoreImpl
extends java.lang.Object
implements ProcessStore

JDBC-based implementation of a process store. Also provides an "in-memory" store by way of HSQL database.

The philsophy here is to keep things simple. Process store operations are relatively infrequent. Performance of the public methods is not a concern. However, note that the ProcessConf objects returned by the class are going to be used from within the engine runtime, and hence their performance needs to be very good. Similarly, these objects should be immutable so as not to confuse the engine. Note the way that the database is used in this class, it is more akin to a recovery log, this is intentional: we want to start up, load stuff from the database and then pretty much forget about it when it comes to reads.
