Class SimpleConnectionProvider  

java.lang.Object
  safejdbc.SimpleConnectionProvider

All Implemented Interfaces:

ConnectionProvider

---

public class SimpleConnectionProvider

extends java.lang.Object

implements ConnectionProvider

This class provides JDBC connection via the JDBC 1 Driver. But this is only an example-implementation and should not be used in real-world-projects, because connections are not cached. This means every call to getConnection() is delegated to the underlying driver. The driver than creates a connection, wich is a very expensive (time consuming) operation.
