Method Detail

makeSubjectLayout

protected abstract Layout<E> makeSubjectLayout(String subjectStr)

return a layout for the subjet string as appropriate for the module. If the subjectStr parameter is null, then a default value for subjectStr should be used.

Parameters:

subjectStr -

Returns:

a layout as appropriate for the module

start

public void start()

Start the appender

Specified by:

start in interface LifeCycle

Overrides:

start in class AppenderBase<E>

append

protected void append(E eventObject)

Perform SMTPAppender specific appending actions, delegating some of them to a subclass and checking if the event triggers an e-mail to be sent.

Specified by:

append in class AppenderBase<E>

subAppend

protected abstract void subAppend(E eventObject)

checkEntryConditions

public boolean checkEntryConditions()

This method determines if there is a sense in attempting to append.

It checks whether there is a set output target and also if there is a set layout. If these checks fail, then the boolean value false is returned.

stop

public void stop()

Specified by:

stop in interface LifeCycle

Overrides:

stop in class AppenderBase<E>

getTo

public List<String> getTo()

Returns value of the To option.

sendBuffer

protected void sendBuffer(E lastEventObject)

Send the contents of the cyclic buffer as an e-mail message.

fillBuffer

protected abstract void fillBuffer(StringBuffer sbuf)

getFrom

public String getFrom()

Returns value of the From option.

getSubject

public String getSubject()

Returns value of the Subject option.

setFrom

public void setFrom(String from)

The From option takes a string value which should be a e-mail address of the sender.

setSubject

public void setSubject(String subject)

The Subject option takes a string value which should be a the subject of the e-mail message.

setSMTPHost

public void setSMTPHost(String smtpHost)

The SMTPHost option takes a string value which should be a the host name of the SMTP server that will send the e-mail message.

getSMTPHost

public String getSMTPHost()

Returns value of the SMTPHost option.

setSMTPPort

public void setSMTPPort(int port)

The port where the SMTP server is running. Default value is 25.

Parameters:

port -

setSSL

public void setSSL(boolean ssl)

setEvaluator

public void setEvaluator(EventEvaluator<E> eventEvaluator)

The EventEvaluator option takes a string value representing the name of the class implementing the EventEvaluators interface. A corresponding object will be instantiated and assigned as the event evaluator for the SMTPAppender.
