# A java logging Handler that delegates to a Ruby logger. The name of the
# j.u.l. logger is used as the progname argument to Logger.add.
#
# The translation between j.u.l. serverity levels and Ruby Logger levels
# isn't exact.
class RubyLoggerHandler < Handler
# NOTE: Since this class overrides a Java class, we have to use the Java
# constructor and set the logger after instantiation. (Overriding in
# JRuby is weird). Use this method to create a new logger that delegates
# to the passed logger.
