  +--com.protomatter.jdbc.pool.JdbcConnectionPoolDriver

All Implemented Interfaces:

java.sql.Driver

public class JdbcConnectionPoolDriver

extends java.lang.Object

implements java.sql.Driver

The driver for use with JDBC connection pools. When this class is loaded, it registers itself with the DriverManager. This driver accepts JDBC connection URLs of the form:

jdbc:protomatter:pool:PoolName

This class also keeps a static reference to the list of all known connection pools, which is updated by creating a new JdbcConnectionPool object. Pools can be un-registered by calling unRegisterPool() on the JdbcConnectionPool object.

Method Detail

getPool

public static JdbcConnectionPool getPool(java.lang.String poolName)

Get one of the currently registered JDBC Connection Pools.

getPoolNames

public static java.util.Enumeration getPoolNames()

Get the list of registered pool names. The returned enumeration contains strings.

shutdownAllConnections

public static void shutdownAllConnections()
