NullLogLite(3pm) User Contributed Perl Documentation NullLogLite(3pm)NAMELog::NullLogLite - The "Log::NullLogLite" class implements the Null Object pattern for the "Log::LogLite" class.SYNOPSISuse Log::NullLogLite; # create new Log::NullLogLite object my $log = new Log::NullLogLite(); ... # we had an error (this entry will not be written to the log # file because we use Log::NullLogLite object). $log->write("Could not open the file ".$file_name.": $!", 4);DESCRIPTIONThe "Log::NullLogLite" class is derived from the "Log::LogLite" class and implement the Null Object Pattern to let us to use the "Log::LogLite" class with null "Log::LogLite" objects. We might want to do that if we use a "Log::LogLite" object in our code, and we do not want always to actually define a "Log::LogLite" object (i.e. not always we want to write to a log file). In such a case we will create a "Log::NullLogLite" object instead of the "Log::LogLite" object, and will use that object instead. The object has all the methods that the "Log::LogLite" object has, but those methods do nothing. Thus our code will continue to run without any change, yet we will not have to define a log file path for the "Log::LogLite" object, and no log will be created.CONSTRUCTORnew ( FILEPATH [,LEVEL [,DEFAULT_MESSAGE ]] ) The constructor. The parameters will not have any affect. Returns the new Log::NullLogLite object.METHODSwrite( MESSAGE [, LEVEL ] ) Does nothing. The parameters will not have any affect. Returns nothing. level( [ LEVEL ] ) Does nothing. The parameters will not have any affect. Returns -1. default_message( [ MESSAGE ] ) Does nothing. The parameters will not have any affect.
