Generally, <tt>inspect</tt> is used if the given object is not a String. A special case is an <tt>Exception</tt> object, which will be printed in detail, including message, class, and backtrace. See #msg2str for the implementation if required." - !ruby/struct:SM::Flow::H level: 3 text: Bugs - !ruby/object:SM::Flow::LIST contents: - !ruby/struct:SM::Flow::LI label: "*" body: Logfile is not locked. - !ruby/struct:SM::Flow::LI label: "*" body: Append open does not need to lock file. - !ruby/struct:SM::Flow::LI label: "*" body: But on the OS which supports multi I/O, records possibly be mixed. type: :BULLET full_name: Logger#add is_singleton: false name: add params: (severity, message = nil, progname = nil, &block) {|| ...} visibility: public
