Field Summary

private boolean	_closeConnectionsWhenFinished Whether or not this OpExecutor should instruct the _connectionFactory to close any open connections after the Op is finished.
private MappedConnectionFactory	_connectionFactory A factory that knows how to access various datasources and is passed on to the instantiated CallExecutors.

Constructor Summary

DirectOpExecutor(java.sql.Connection connection, TraceKey traceKey)

DirectOpExecutor(MappedConnectionFactory connectionFactory)

Method Summary

Op	executeOp(Op op) Evaluate the Op's options, construct the appropriate CallExecutor and invoke the Op's _execute method.
void	setCloseConnectionsWhenFinished(boolean closeConnectionsWhenFinished) In the finally block of the executeOp method, tell the MappedConnectionFactory to close all the connections that it has open.

_connectionFactory

private MappedConnectionFactory _connectionFactory

DirectOpExecutor

public DirectOpExecutor(java.sql.Connection connection,
                        TraceKey traceKey)

Method Detail

setCloseConnectionsWhenFinished

public void setCloseConnectionsWhenFinished(boolean closeConnectionsWhenFinished)

In the finally block of the executeOp method, tell the MappedConnectionFactory to close all the connections that it has open.

Parameters:

closeConnectionsWhenFinished - whether or not to tell the MappedConnectionFactory to close all open connections

executeOp

public Op executeOp(Op op)
             throws OpException

Evaluate the Op's options, construct the appropriate CallExecutor and invoke the Op's _execute method. The method is not directly invoked; rather the CallExecutor's executeOp method is. If the options have a non-null object at the HandlingOption.PROP_DBUNIT_LOAD_SET key, a CallExecutorDBUnit will be instantiated and used. If otherwise, a typical CallExecutorDB will be instantiated and used.

Specified by:

executeOp in interface OpExecutor

Parameters:

op - the Op to execute

Returns:

the op after execution, it will be the same object

Throws:

OpException

java.lang.NullPointerException - if the op parameter is null
