 winstone.jndi.resourceFactories.WinstoneDataSource
| WinstoneDataSource | | public class WinstoneDataSource implements DataSource,Runnable(Code) | | Implements a JDBC 2.0 pooling datasource. This is meant to act as a wrapper
around a JDBC 1.0 driver, just providing the pool management functions.
Supports keep alives, and check-connection-before-get options, as well
as normal reclaimable pool management options like maxIdle, maxConnections and
startConnections. Additionally it supports poll-retry on full, which means the
getConnection call will block and retry after a certain period when the pool
is maxed out (good for high load conditions).
This class was originally drawn from the generator-runtime servlet framework and
modified to make it more JDBC-API only compliant.

| WinstoneDataSource | | public WinstoneDataSource(String name, Map args, ClassLoader loader)(Code) | | Main constructor. Basically just calls the init method
|
| destroy | | public void destroy()(Code) | | Close this pool - probably because we will want to re-init the pool
|
| executeKeepAliveOnUnused | | protected void executeKeepAliveOnUnused()(Code) | | Executes keep alive for each of the connections in the supplied pool
|
| getConnection | | protected Connection getConnection(int retriesAllowed) throws SQLException(Code) | | Get a read-write connection - preferably from the pool, but fresh if needed
|
| getLoginTimeout | | public int getLoginTimeout()(Code) | | |
| killPooledConnections | | protected void killPooledConnections(List pool, int maxIdleCount)(Code) | | Iterates through a list and kills off unused connections until we reach the
minimum idle count for that pool.
|
| makeNewRealConnection | | protected Connection makeNewRealConnection(List pool) throws SQLException(Code) | | This makes a new rw connection. It assumes that the synchronization has taken
place in the calling code, so is unsafe for use outside this class.
|
| run | | public void run()(Code) | | Clean up and keep-alive thread.
Note - this needs a lot more attention to the semaphore use during keepAlive etc
|
| setLoginTimeout | | public void setLoginTimeout(int timeout)(Code) | | |
