Constructor Detail

ConnectionPool

public ConnectionPool(int size,
                      ConnectionFactory connSource,
                      int connectionTimeout,
                      String testQuery,
                      boolean testOnBorrow)
               throws SQLException

Deprecated.

Constructor.

Parameters:

size - The size of the pool.

connSource - The ConnectionFactory to use.

seconds - The timeout for old connections in the pool.

testQuery - A test query to validate connection liveness.

testOnBorrow - Should connections be tested when borrowed or not? If true then connections will be tested when gotten:

• for a connection from the pool, a failing test will retry with another connection
• for new connections (i.e. when pool is empty), a failing test will be thrown to the application

Throws:

SQLException

Method Detail

getSize

public int getSize()

Deprecated.

Get the current size of the available pool.

Returns:

int The current size. Does NOT include connections that are currently being used!

getPooledConnection

public PooledConnection getPooledConnection()
                                     throws SQLException

Deprecated.

Get a PooledConnection instance from the pool.

Returns:

PooledConnection The instance.

Throws:

SQLException - On error.

putInPool

protected void putInPool(PooledConnection pc)

Deprecated.

putBack

public void putBack(XPooledConnection conn)

Deprecated.

Puts back a connection after usage. This method should be called by DataSource objects.

Parameters:

conn - The connection. If the connection has been invalidated, or if the pool is large enough, then this method will actually close the connection.

getOldConnections

protected Enumeration getOldConnections()

Deprecated.

run

public void run()

Deprecated.

Specified by:

run in interface Runnable

cleanup

public void cleanup()

Deprecated.

To be called when the pool of connections is no longer needed. This method will close all connections in the pool.
