Class ERMemoryAdaptor

java.lang.Object

com.webobjects.eoaccess.EOAdaptor

er.memoryadaptor.ERMemoryAdaptor

public class ERMemoryAdaptor
extends EOAdaptor

ERMemoryAdaptor is an EOAdaptor implementation that runs entirely in memory. There is currently no persistent datastore, but this provides a useful mechanism for writing testcases or simply testing a model without the overhead of setting up a database. Internally, ERMemoryAdaptor just keeps a dictionary that maps entities to arrays of row dictionaries (it looks a lot like the snapshot cache).
