All Implemented Interfaces:
PropertySet

public class JDBCPropertySet
extends AbstractPropertySet

This is an implementation of a property set manager for JDBC. It relies on one table, called "property," that has three columns: "type" (integer), "key" (string), and "value" (string). This is not likely to be enough for people who store BLOBS as properties. Of course, those people need to get a life.
