Class JdbcPreparedStatementHandle

java.lang.Object

bitronix.tm.resource.jdbc.BaseProxyHandlerClass

bitronix.tm.resource.jdbc.JdbcPreparedStatementHandle

All Implemented Interfaces:

InvocationHandler

public class JdbcPreparedStatementHandle
extends BaseProxyHandlerClass

Caching PreparedStatement wrapper.

This class is a proxy handler for a PreparedStatement. It does not implement the PreparedStatement interface or extend a class directly, but you methods implemented here will override those of the underlying delegate. Simply implement a method with the same signature, and the local method will be called rather than the delegate.

isWrapperFor

public boolean isWrapperFor(Class<?> iface)
                     throws SQLException

Throws:

SQLException

unwrap

public <T> T unwrap(Class<T> iface)
             throws SQLException

SQLException

setPooledConnection

protected void setPooledConnection(JdbcPooledConnection pooledConnection)

Set the parent connection that created this statement. We need this to return the PreparedStatement to the pool.

Parameters:

pooledConnection - the parent JdbcPooledConnection

getPooledConnection

protected JdbcPooledConnection getPooledConnection()

getDelegateUnchecked

protected PreparedStatement getDelegateUnchecked()

setDelegate

protected void setDelegate(PreparedStatement delegate)

getProxiedDelegate

public Object getProxiedDelegate()
                          throws Exception

Description copied from class: BaseProxyHandlerClass

Must be implemented by the sub-class of this class. This method should return the "true" object to be delegated to in the case that the method is not overridden by the sub-class.

Specified by:

getProxiedDelegate in class BaseProxyHandlerClass

Returns:

the true delegate object

Throws:

Exception - can throw any exception if desired

equals

public boolean equals(Object obj)

Overridden equals() that takes all PreparedStatement attributes into account.

Overrides:

toString

public String toString()

Overrides:

close

public void close()
           throws SQLException

Throws:

SQLException

isClosed

public boolean isClosed()
                 throws SQLException

Throws:

SQLException
