Inherits:
Object show all
Defined in:
lib/origen/log.rb

Overview

An instance of this class is instantiated as Origen.log and provides the following API

Examples:

log.error "Blah"     # Error message, always shown
log.debug "Blah"     # Debug message, only shown when in verbose mode
log.info  "Blah"     # Info message, always shown
log.warn  "Blah"     # Warning message, always shown
log.deprecate "Blah" # Deprecate message, always shown

Class Method Details

  Origen.log.info "This will not appear in the log file!"
end
