Constructor Details

MailSender

public MailSender(Channel componentChannel)

Creates a new component base with its channel set to the given channel.

As a special case Channel.SELF can be passed to the constructor to make the component use itself as channel. The special value is necessary as you obviously cannot pass an object to be constructed to its constructor.

Parameters:

componentChannel - the channel that the component’s handlers listen on by default and that Manager.fire(Event, Channel...) sends the event to

Method Details

connectionsGenerate

protected boolean connectionsGenerate()

Description copied from class: ConnectionManager

If connections are event generators, register the component as generator upon the creation of the first connection and unregister it when closing the last one.

Specified by:

connectionsGenerate in class ConnectionManager<MailSender.SenderChannel>

Returns:

true, if connections generate

setMailProperties

public MailSender setMailProperties(Map<String,String> props)

Sets the mail properties.

See the Jakarta Mail documentation for available settings.

Overrides:

setMailProperties in class MailConnectionManager<MailSender.SenderChannel,Event<?>>

Parameters:

props - the props

Returns:

the mail monitor

setMaxIdleTime

public MailSender setMaxIdleTime(Duration maxIdleTime)

Sets the maximum idle time.

An open connection to the mail server is closed after this time.

Parameters:

maxIdleTime - the new max idle time

maxIdleTime

public Duration maxIdleTime()

Returns the max idle time.

Returns:

the duration

configureComponent

protected void configureComponent(Map<String,String> values)

Description copied from class: MailConnectionManager

Configure the component specific values.

Specified by:

configureComponent in class MailConnectionManager<MailSender.SenderChannel,Event<?>>

Parameters:

values - the values

onStart

@Handler
public void onStart(Start event)
             throws MessagingException

Start the component.

Parameters:

event - the event

Throws:

MessagingException

onOpenMailSender

@Handler
public void onOpenMailSender(OpenMailSender event,
 Channel channel)
                      throws MessagingException

Open a connection for sending mail as specified by the event.

Properties configured for the component are used as fallbacks, so simply sending an event without specific properties opens another system connection.

Parameters:

event - the event

channel - the channel

Throws:

MessagingException

onMessage

@Handler
public void onMessage(SendMailMessage event,
 Channel channel)
               throws MessagingException

Sends the message as specified by the event.

Parameters:

event - the event

MessagingException - the messaging exception
