Constructor Details

#initialize(logger, level, data, caller_tracing) ⇒ LogEvent

call-seq:

LogEvent.new( logger, level, [data], caller_tracing )

Creates a new log event with the given logger name, numeric level, array of data from the user to be logged, and boolean caller_tracing flag. If the caller_tracing flag is set to true then Kernel::caller will be invoked to get the execution trace of the logging method.
