LF5Appender
public LF5Appender()
- Constructs a
LF5Appender using the default instance of
the LogBrokerMonitor. This constructor should always
be preferred over the
LF5Appender(LogBrokerMonitor monitor)
constructor, unless you need to spawn additional log monitoring
windows.
LF5Appender
public LF5Appender(org.apache.log4j.lf5.viewer.LogBrokerMonitor monitor)
- Constructs a
LF5Appender using an instance of
a LogBrokerMonitor supplied by the user. This
constructor should only be used when you need to spawn
additional log monitoring windows.
- Parameters:
monitor - An instance of a LogBrokerMonitor
created by the user.
append
public void append(LoggingEvent event)
- Appends a
LoggingEvent record to the
LF5Appender.
- Overrides:
append in class AppenderSkeleton
- Parameters:
event - The LoggingEvent
to be appended.
close
public void close()
- This method is an empty implementation of the close() method inherited
from the
org.apache.log4j.Appender interface.
requiresLayout
public boolean requiresLayout()
- Returns a value that indicates whether this appender requires a
Layout. This method always returns false.
No layout is required for the LF5Appender.
setCallSystemExitOnClose
public void setCallSystemExitOnClose(boolean callSystemExitOnClose)
- This method is used to set the property that controls whether
the
LogBrokerMonitor is hidden or closed when a user
exits
the monitor. By default, the LogBrokerMonitor will hide
itself when the log window is exited, and the swing thread will
continue to run in the background. If this property is
set to true, the LogBrokerMonitor will call System.exit(0)
and will shut down swing thread and the virtual machine.
- Parameters:
callSystemExitOnClose - A boolean value indicating whether
to call System.exit(0) when closing the log window.
equals
public boolean equals(LF5Appender compareTo)
- The equals method compares two LF5Appenders and determines whether
they are equal. Two
Appenders will be considered equal
if, and only if, they both contain references to the same
LogBrokerMonitor.
- Parameters:
compareTo - A boolean value indicating whether
the two LF5Appenders are equal.
getLogBrokerMonitor
public org.apache.log4j.lf5.viewer.LogBrokerMonitor getLogBrokerMonitor()

- Returns:
- The default instance of the
LogBrokerMonitor.
