Method Detail

makeSubjectLayout

protected abstract Layout<E> makeSubjectLayout(java.lang.String subjectStr)

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

Parameters:

subjectStr - the desired subject

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>

eventMarksEndOfLife

protected abstract boolean eventMarksEndOfLife(E eventObject)

subAppend

protected abstract void subAppend(CyclicBuffer<E> cb,
                                  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.

Returns:

true if appender is setup properly

stop

public void stop()

Specified by:

stop in interface LifeCycle

Overrides:

stop in class AppenderBase<E>

getToList

public java.util.List<PatternLayoutBase<E>> getToList()

Returns value of the toList option.

Returns:

list of pattern layout

sendBuffer

protected void sendBuffer(CyclicBuffer<E> cb,
                          E lastEventObject)

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

Parameters:

cb - the cyclic buffer

lastEventObject - the log event

fillBuffer

protected abstract void fillBuffer(CyclicBuffer<E> cb,
                                   java.lang.StringBuffer sbuf)

getFrom

public java.lang.String getFrom()

Returns value of the From option.

Returns:

the value of "from"

getSubject

public java.lang.String getSubject()

Returns value of the Subject option.

Returns:

the subject text

setFrom

public void setFrom(java.lang.String from)

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

Parameters:

from - desired value of "from" field

setSubject

public void setSubject(java.lang.String subject)

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

Parameters:

subject - desired subject text

setSMTPHost

public void setSMTPHost(java.lang.String smtpHost)

Alias for smtpHost

Parameters:

smtpHost - desired alias for SMTP host

setSmtpHost

public void setSmtpHost(java.lang.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.

Parameters:

smtpHost - desired SMTP hostname

getSMTPHost

public java.lang.String getSMTPHost()

Alias for getSmtpHost().

Returns:

the SMTP hostname

getSmtpHost

public java.lang.String getSmtpHost()

Returns value of the SMTPHost option.

Returns:

the SMTP hostname

setSMTPPort

public void setSMTPPort(int port)

Alias for setSmtpPort(int).

Parameters:

Useful in case the hostname for the client host is not fully qualified and as a consequence the SMTP server rejects the clients HELO/EHLO command.

Parameters:

localhost - the localhost name

getCyclicBufferTracker
