Class DataSourceWrapper

java.lang.Object

de.aristaflow.adept2.base.registry.dbconfiguration.DataSourceWrapper

All Implemented Interfaces:

java.sql.Wrapper, javax.sql.CommonDataSource, javax.sql.DataSource

public class DataSourceWrapper
extends java.lang.Object
implements javax.sql.DataSource

A simple wrapper for a JDBCDataSource which is required by DatabaseConfiguration. Note that only getConnection() is implemented. All other methods throw an UnsupportedOperationException.
This implementation needs to be changed as soon as DatabaseConfiguration uses more than getConnection().
