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.

Constructor Summary

SimpleConnectionProvider(java.lang.String url, java.util.Properties info, java.lang.String drivername)
This constructor initializes the driver using a map containing login information.

SimpleConnectionProvider(java.lang.String user, java.lang.String password, java.lang.String url, java.lang.String drivername)
This constructor initializes the driver via separate strings.

Method Summary

java.sql.Connection

getConnection() This method is called by the framework to yield a database connection.
