Method Detail

activateOptions

public void activateOptions()

Description copied from interface: OptionHandler

Activate the options that were previously set with calls to option setters.

This allows to defer activiation of the options until all options have been set. This is required for components which have related options that remain ambigous until all are set.

For example, the FileAppender has the File and Append options both of which are ambigous until the other is also set.

format

public String format(LoggingEvent event)

Returns the log statement in a format consisting of the level, followed by " - " and then the message. For example,

 INFO - "A message"

The category parameter is ignored.

public boolean ignoresThrowable()

The SimpleLayout does not handle the throwable contained within LoggingEvents. Thus, it returns true.

Overrides:: ignoresThrowable in class Layout
