Java Source Code / Java Documentation » Database JDBC Connection Pool » SmartPool » org.smartlib.pool.core   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    org.smartlib.pool.core.ConnectionPool ConnectionPool public class ConnectionPool implements Pool,PoolMonitor(Code) This class implements the Pool interface and thus is responsible for managing a single pool of connections. Field Summary  Logger logger      Constructor Summary   ConnectionPool(PoolConfig config, String name)      Method Summary public  void addConnectionLeakListener(ConnectionLeakListener cle)      This method adds a connection leak listener. public  ConfigMonitor getConfigMonitor()      This method returns an instance of ConfigMonitor. public  Connection getConnection()      This method returns a Connection from the connection pool. public  Connection getConnection(String owner)      This method returns a Connection from the pool. The owner of this connection is identified by owner . Note: This method blocks if the pool size has reached it's maximum size and no free connections are available until a free connection is available. public  Vector getConnectionLeakListeners()      public  Vector getConnectionsInUse()      public  int getCurrentPoolSize()      This method returns the current size of the pool. public  String getName()      public  int getNoOfFreeConnections()      public  void releaseConnections()      This method releases excessive connections, i.e it actully closes them. public  void removeConnectionLeakListener(ConnectionLeakListener cle)      This method removes a connection leak listener. public  void returnConnection(Connection ret)      This method releases the connection back to the pool. public  void shutDown()      Field Detail logger Logger logger(Code) Constructor Detail ConnectionPool ConnectionPool(PoolConfig config, String name) throws ConnectionPoolException(Code) Constructor initialises the pool as per the configuration specified by config Method Detail addConnectionLeakListener public void addConnectionLeakListener(ConnectionLeakListener cle) throws ConnectionPoolException(Code) This method adds a connection leak listener. The methods of cle will be called when a leak is detected as per the pool configuration. Parameters:   cle - Class implementing ConnectionLeakListener interface. exception:   ConnectionPoolException - if there is any problemadding ConnectionLeakListener. getConfigMonitor public ConfigMonitor getConfigMonitor()(Code) This method returns an instance of ConfigMonitor. ConfigMonitor for monitoring the configuration of the pool atruntime. getConnection public Connection getConnection() throws ConnectionPoolException(Code) This method returns a Connection from the connection pool. The owner of this pool is marked as N/A indicating unknown/anonymous. Note: This method blocks if the pool size has reached it's maximum size and no free connections are available until a free connection is available. The time period for which this method blocks depends on the connection-wait-time-out specified in the configuration file. Connection from the pool. exception:   ConnectionPoolException - if there is any problemgetting connection. getConnection public Connection getConnection(String owner) throws ConnectionPoolException(Code) This method returns a Connection from the pool. The owner of this connection is identified by owner . Note: This method blocks if the pool size has reached it's maximum size and no free connections are available until a free connection is available. The time period for which this method blocks depends on the connection-wait-time-out specified in the configuration file. Parameters:   owner - String identifying the owner. Connection from the pool exception:   ConnectionPoolException - if there is any problemgetting connection. getConnectionLeakListeners public Vector getConnectionLeakListeners()(Code) Vector of registered ConnectionLeakListeners. getConnectionsInUse public Vector getConnectionsInUse()(Code) Vector of connections in use. getCurrentPoolSize public int getCurrentPoolSize()(Code) This method returns the current size of the pool. Current size of the pool. getName public String getName()(Code) getNoOfFreeConnections public int getNoOfFreeConnections()(Code) Number of free connections in the pool. releaseConnections public void releaseConnections()(Code) This method releases excessive connections, i.e it actully closes them. removeConnectionLeakListener public void removeConnectionLeakListener(ConnectionLeakListener cle) throws ConnectionPoolException(Code) This method removes a connection leak listener. cle will not get any further notifications. Parameters:   cle - Class implementing ConnectionLeakListener interface. exception:   ConnectionPoolException - If there is any problemremoving ConnectionLeakListener. returnConnection public void returnConnection(Connection ret)(Code) This method releases the connection back to the pool. Parameters:   ret - connection to be released shutDown public void shutDown()(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
