Constructor Detail ConnectionPool public ConnectionPool(String name, int poolSize, int maxSize, long expiryTime, String url, String username, String password)(Code) Creates new connection pool. Parameters:   name - pool name Parameters:   poolSize - maximum number of pooled objects, or 0 for no limit Parameters:   maxSize - maximum number of possible objects, or 0 for no limit Parameters:   expiryTime - expiry time (milliseconds) for pooled object, or 0 for no expiry Parameters:   url - JDBC connection URL Parameters:   username - database username Parameters:   password - password for the database username supplied ConnectionPool public ConnectionPool(String name, int poolSize, int maxSize, long expiryTime, String url, Properties props)(Code) Creates new connection pool. Parameters:   name - pool name Parameters:   poolSize - maximum number of pooled objects, or 0 for no limit Parameters:   maxSize - maximum number of possible objects, or 0 for no limit Parameters:   expiryTime - expiry time (milliseconds) for pooled object, or 0 for no expiry Parameters:   url - JDBC connection URL Parameters:   props - connection properties Method Detail addConnectionPoolListener final public void addConnectionPoolListener(ConnectionPoolListener x)(Code) Adds an ConnectionPoolListener to the event notification list. compareTo public int compareTo(Object o)(Code) Compares this instances to other instances by name. create protected Reusable create() throws SQLException(Code) Creates a new database connection. destroy protected void destroy(Reusable o)(Code) Closes the given connection. freeConnection protected void freeConnection(Connection c) throws SQLException(Code) Returns a connection to the pool (for internal use only). Connections obtained from the pool should be returned by calling the close() method on the connection. getConnection public Connection getConnection() throws SQLException(Code) Gets a connection from the pool. getConnection public Connection getConnection(long timeout) throws SQLException(Code) Gets a connection from the pool. getPasswordDecoder public PasswordDecoder getPasswordDecoder()(Code) Returns the current password decoder class. getValidator public ConnectionValidator getValidator()(Code) Returns the current validator class. isValid protected boolean isValid(Reusable o)(Code) Validates a connection. removeConnectionPoolListener final public void removeConnectionPoolListener(ConnectionPoolListener x)(Code) Removes an ConnectionPoolListener from the event notification list. setCaching public void setCaching(boolean b)(Code) Determines whether to perform statement caching. This applies to all types of statements (normal, prepared, callable). setCaching public void setCaching(boolean ss, boolean ps, boolean cs)(Code) Determines whether to perform statement caching. Parameters:   ss - whether to cache Statement objects Parameters:   ps - whether to cache PreparedStatement objects Parameters:   cs - whether to cache CallableStatement objects setPasswordDecoder public void setPasswordDecoder(PasswordDecoder pd)(Code) Sets the password decoder class. setValidator public void setValidator(ConnectionValidator cv)(Code) Sets the validator class for connections. toString public String toString()(Code) Returns a descriptive string for this pool instance.
