All Implemented Interfaces:

ConnectorCapabilities

public class SimpleCapabilities
extends JDBCCapabilities
implements ConnectorCapabilities

This is a "simple" capabilities class that allows criteria but no complicated joins, subqueries, etc to be passed to the connector. This capabilities class may come in handy for testing and for sources that support JDBC but don't support extended JDBC capabilities.
