public class PoolableCallableStatement
extends DelegatingCallableStatement

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

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

Since:

2.0

Constructor Detail

PoolableCallableStatement

public PoolableCallableStatement(CallableStatement callableStatement,
                                 PStmtKey key,
                                 KeyedObjectPool<PStmtKey,DelegatingPreparedStatement> pool,
                                 DelegatingConnection<Connection> connection)

Constructor.

Parameters:

callableStatement - the underlying CallableStatement

key - the key for this statement in the KeyedObjectPool

pool - the KeyedObjectPool from which this CallableStatement was obtained

connection - the DelegatingConnection 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 AutoCloseable

Specified by:

close in interface Statement

Overrides:

close in class DelegatingStatement

Throws:

SQLException

activate

public 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 - thrown by the delegating statement.

Since:

2.4.0 made public, was protected in 2.3.0.

passivate

public 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 - thrown by the delegating statement.

Since:

2.4.0 made public, was protected in 2.3.0.
