Implementations of this interface should be immutable, and should offer public, no argument constructors.

The methods are handed raw, physical database Connections, not c3p0-generated proxies.

Although c3p0 will ensure this with respect to state controlled by standard JDBC methods, any modifications of vendor-specific state shold be made consistently so that all Connections in the pool are interchangable.

This method is only called once per Connection. If standard JDBC Connection properties are modified — specifically catalog, holdability, transactionIsolation, readOnly, and typeMap — those modifications will override defaults throughout the Connection's tenure in the pool.
