Method Detail

configure

public void configure()
               throws ConfigurationException

Description copied from interface: ISender

configure() is called once at startup of the framework in the configure method of the owner of this sender. Purpose of this method is to check whether the static configuration of the sender is correct. As much as possible class-instantiating should take place in the configure() or open() method, to improve performance.

Specified by:

configure in interface IConfigurable

Specified by:

configure in interface ISender

Overrides:

configure in class SenderWithParametersBase

Throws:

ConfigurationException

open

public void open()
          throws SenderException

Description copied from interface: ISender

This method will be called to start the sender. After this method is called the sendMessage method may be called. Purpose of this method is to reduce creating connections to databases etc. in the sendMessage() method.

Specified by:

open in interface ISender

Overrides:

open in class SenderBase

Throws:

SenderException

isSynchronous

public boolean isSynchronous()

Description copied from interface: ISender

When true, the result of sendMessage is the reply of the request.

Specified by:

isSynchronous in interface ISender

Overrides:

isSynchronous in class SenderBase

sendMessage

public SenderResult sendMessage(Message message,
                                PipeLineSession session)
                         throws SenderException

Description copied from interface: ISender

Send a message to some destination (as configured in the Sender object). This method may only be called after the configure() method is called.

The following table shows the difference between synchronous and a-synchronous senders:

	synchronous	a-synchronous
ISender.isSynchronous() returns	true	false
return value of sendMessage() is	the reply-message	the messageId of the message sent
the correlationID specified with sendMessage()	may be ignored	is sent with the message
a {link TimeOutException}	may be thrown if a timeout occurs waiting for a reply	should not be expected

Multiple objects may try to call this method at the same time, from different threads. Implementations of this method should therefore be thread-safe, or synchronized.

Throws:

SenderException

setCronExpressionPattern

public void setCronExpressionPattern(String string)

expression that generates the cron trigger

setJobGroup

public void setJobGroup(String string)

job group in which the new trigger is to be created (optional)

setJobNamePattern

public void setJobNamePattern(String string)

pattern that leads to the name of the registered trigger(optional)

setJavaListener

public void setJavaListener(String string)

java listener to be called when scheduler trigger fires

getSchedulerHelper

public SchedulerHelper getSchedulerHelper()

setSchedulerHelper

public void setSchedulerHelper(SchedulerHelper helper)
