Constructor Detail

LogSystemCommonsLog

public LogSystemCommonsLog()

LogSystemCommonsLog

public LogSystemCommonsLog(java.lang.String name)

LogSystemCommonsLog

public LogSystemCommonsLog(boolean pst)

Lets you set whether or not this instance should print the full stack trace of exceptions and errors passed to it.

It should be possible to create a LogFactory implementation that takes advantage of this constructor.

Parameters:

pst - if true, stack traces will be printed

LogSystemCommonsLog

public LogSystemCommonsLog(boolean pst,
