log
protected void log(java.lang.String level, java.lang.String message)
Logs the specified message at the specified level.This method is called internally by the

,warn(String)
,info(String)
anddebug(String)
methods, with thelevel

", or "DEBUG
" respectively.The default implementation of this method sends the the output of
BasicLogFormatter.format
(level,message,
getName()
)
to theWriter
specified in the class constructor, and then flushes it.Overriding this method in a subclass provides a convenient means of logging to a
Writer
using a different format.- Parameters:
