 org.enhydra.jdbc.pool.StandardPoolDataSource
All known Subclasses: org.enhydra.jdbc.pool.StandardXAPoolDataSource,
| StandardPoolDataSource | | public class StandardPoolDataSource extends CoreDataSource implements DataSource,PoolHelper,ConnectionEventListener(Code) | | StandardPoolDataSource class allows to make some operations on
PooledConnection. It implements PoolHelper for the 3 methods :
create : create a PooledConnection
create(user,password) : create a PooledConnection with an other user/password
testThisObject : check if the object is still valid
checkThisObject : check if the object is closed
expire : kill the object
|
| onOff | | public boolean onOff(Code) | | |
| StandardPoolDataSource | | public StandardPoolDataSource()(Code) | | Constructor
|
| StandardPoolDataSource | | public StandardPoolDataSource(int initSize)(Code) | | Constructor
|
| checkThisObject | | public boolean checkThisObject(Object o)(Code) | | This method tests if a connection is closed or not
|
| connectionClosed | | public void connectionClosed(ConnectionEvent event)(Code) | | Invoked when the application calls close()
on its representation of the connection
|
| connectionErrorOccurred | | public void connectionErrorOccurred(ConnectionEvent event)(Code) | | connectionErrorOccurred and connectionClosed are methods
from ConnectionEventListener interface
Invoked when a fatal connection error occurs,
just before an SQLException is thrown to the application
|
| expire | | public void expire(Object o)(Code) | | object specific work to kill the object
|
| getCheckLevelObject | | public int getCheckLevelObject()(Code) | | |
| getConnection | | public Connection getConnection() throws SQLException(Code) | | getConnection allows to get an object from the pool and returns it
to the user. In this case, we return an PooledConnection
|
| getConnection | | public Connection getConnection(String _user, String _password) throws SQLException(Code) | | getConnection allows to get an object from the pool and returns it
to the user. In this case, we return an PooledConnection
|
| getDeadLockMaxWait | | public long getDeadLockMaxWait()(Code) | | |
| getDeadLockRetryWait | | public long getDeadLockRetryWait()(Code) | | |
| getGeneration | | public int getGeneration()(Code) | | |
| getLifeTime | | public long getLifeTime()(Code) | | |

| getMaxSize | | public int getMaxSize()(Code) | | |
| getMinSize | | public int getMinSize()(Code) | | |
| getReference | | public Reference getReference() throws NamingException(Code) | | Retrieves the Reference of this object. Used at binding time by JNDI
to build a reference on this object.
The non-null Reference of this object.
exception:
NamingException - If a naming exception was encountered whileretrieving the reference. |
| getSleepTime | | public long getSleepTime()(Code) | | |
| getUnlockedObjectCount | | public int getUnlockedObjectCount()(Code) | | |
| isGC | | public boolean isGC()(Code) | | |
| setCheckLevelObject | | public void setCheckLevelObject(int checkLevelObject)(Code) | | set the check level of the pooled object before using them
Parameters:
checkLevelObject - (
0 = no special checking1 = just a check on an object2 = test the object3 = just a check on an object (for all the objects)4 = test the object (for all the objects) |
| setDataSourceName | | public void setDataSourceName(String dataSourceName)(Code) | | Set up the data source name, get the initial context,
and lookup in JNDI to obtain a reference of the DataSourceName
this method must be called before a getConnection (in this case
an exception is returned
|
| setDeadLockMaxWait | | public void setDeadLockMaxWait(long deadLock)(Code) | | set the global time the pool can wait for a free object
Parameters:
deadLock - in milliseconds |
| setDeadLockRetryWait | | public void setDeadLockRetryWait(long loopWait)(Code) | | set the time before 2 tries when trying to obtain an object from the pool
Parameters:
loopWait - in milliseconds |
| setDebug | | public void setDebug(boolean debug)(Code) | | set the debug flag
Parameters:
debug - a boolean flag |
| setGC | | public void setGC(boolean gc)(Code) | | set the garbage collection option
Parameters:
gc - true: the garbage collector will be launched when clean up of thepool, else false |
| setGeneration | | public void setGeneration(int generation)(Code) | | set the generation number for future connection, the generation number
is used to identify a group a created objects
Parameters:
generation - an integer value which represents a generation |
| setJdbcTestStmt | | public void setJdbcTestStmt(String jdbcTestStmt)(Code) | | set the String to test the jdbc connection before using it
Parameters:
jdbcTestStmt - an sql statement |
| setLifeTime | | public void setLifeTime(long lifeTime)(Code) | | set the life time of the pooled objects
Parameters:
lifeTime - life time of the pooled objects (in milliseconds) |
| setLogWriter | | public void setLogWriter(PrintWriter logWriter)(Code) | | set the logwriter for the current object, the logwriter will be use by
the current object and by the generic pool
Parameters:
logWriter - a PrintWriter object |
