public class PoolableCallableStatement
extends DelegatingCallableStatement
implements CallableStatement

A DelegatingCallableStatement that cooperates with PoolingConnection to implement a pool of CallableStatements.

The close() method returns this statement to its containing pool. (See PoolingConnection.)

Constructor Detail

PoolableCallableStatement

public PoolableCallableStatement(CallableStatement stmt,
                                 Object key,
                                 KeyedObjectPool pool,
                                 Connection conn)
Constructor.

Parameters:
stmt - the underlying CallableStatement
key - the key for this statement in the KeyedObjectPool
pool - the KeyedObjectPool from which this CallableStatement was obtained
conn - the Connection that created this CallableStatement
Method Detail

close

public void close()
           throws SQLException
Returns the CallableStatement to the pool. If {DelegatingStatement.isClosed(), this is a No-op.

Specified by:
close in interface Statement
Overrides:
close in class DelegatingStatement
Throws:
SQLException

activate

protected void activate()
                 throws SQLException
Activates after retrieval from the pool. Adds a trace for this CallableStatement to the Connection that created it.

Overrides:
activate in class DelegatingStatement
Throws:
SQLException

passivate

protected void passivate()
                  throws SQLException
Passivates to prepare for return to the pool. Removes the trace associated with this CallableStatement from the Connection that created it. Also closes any associated ResultSets.

Overrides:
passivate in class DelegatingStatement
Throws:
SQLException
