Method Summary

Modifier and Type	Method	Description
void	configure()	configure() is called once at startup of the framework in the configure method of the owner of this sender.
default boolean	consumesSessionVariable(String sessionKey)	returns true if the sender or one of its children use the named session variable.
default boolean	isSynchronous()	When true, the result of sendMessage is the reply of the request.
SenderResult	sendMessage(Message message, PipeLineSession session)	Send a message to some destination (as configured in the Sender object).
default Message	sendMessageOrThrow(Message message, PipeLineSession session)
void	start()	This method will be called to start the sender.
void	stop()	Stop/close the sender and deallocate resources.

Method Details

configure

void configure()
        throws ConfigurationException

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

Throws:

ConfigurationException

start

void start()

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.

stop

void stop()

Stop/close the sender and deallocate resources.

isSynchronous

default boolean isSynchronous()

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

sendMessage

@Nonnull
SenderResult sendMessage(@Nonnull
 Message message,
 @Nonnull
 PipeLineSession session)
                  throws SenderException,
TimeoutException

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
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

TimeoutException

sendMessageOrThrow

@Nonnull
default Message sendMessageOrThrow(@Nonnull
 Message message,
 @Nonnull
 PipeLineSession session)
                            throws SenderException,
TimeoutException

Throws:

SenderException

TimeoutException

consumesSessionVariable

default boolean consumesSessionVariable(String sessionKey)

returns true if the sender or one of its children use the named session variable. Callers can use this to determine if a message needs to be preserved.
