NullLogLite(3pm) User Contributed Perl Documentation NullLogLite(3pm) NAME
Log::NullLogLite - The "Log::NullLogLite" class implements the Null Object pattern for the "Log::LogLite" class. SYNOPSIS
use 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); DESCRIPTION
The "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. CONSTRUCTOR
new ( FILEPATH [,LEVEL [,DEFAULT_MESSAGE ]] ) The constructor. The parameters will not have any affect. Returns the new Log::NullLogLite object. METHODS
write( 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. Returns empty string (""). AUTHOR

Log::Report::Dispatcher::Perl(3pm) User Contributed Perl Documentation Log::Report::Dispatcher::Perl(3pm) NAME
Log::Report::Dispatcher::Perl - send messages to die and warn INHERITANCE
Log::Report::Dispatcher::Perl is a Log::Report::Dispatcher SYNOPSIS
dispatcher Log::Report::Dispatcher::Perl => 'default' , accept => 'NOTICE-'; # close the default dispatcher dispatcher close => 'default'; DESCRIPTION
Ventilate the problem reports via the standard Perl error mechanisms: "die()", "warn()", and "print()". There can be only one such dispatcher (per thread), because once "die()" is called, we are not able to return. Therefore, this dispatcher will always be called last. In the early releases of Log::Report, it tried to simulate the behavior of warn and die using STDERR and exit; however: that is not possible. METHODS
