Pipeline::Base(3) User Contributed Perl Documentation Pipeline::Base(3)NAMEPipeline::Base - base class for all classes in Pipeline distribution
SYNOPSIS
use Pipeline::Base;
$object = Pipeline::Base->new()
$object->debug( 10 );
$object->emit("message");
DESCRIPTION
"Pipeline::Base" is a class that provides a basic level of
functionality for all classes in the Pipeline system. Most importantly
it provides the construction and initialization of new objects.
METHODS
CLASS->new()
The "new()" method is a constructor that returns an instance of
receiving class.
init( LIST );
"init()" is called by the constructor, "new()" and is passed all of
its arguments in LIST.
debug( [ SCALAR ] )
The "debug()" method gets and sets the debug state of the OBJECT.
Setting it to a true value will cause messages sent to "emit()" to
be printed to the terminal. If debug() is called as a class method
it always will return true.
emit( SCALAR )
"emit()" is a debugging tool. It will cause the the SCALAR to be
formatted and sent to the "log()" method if the current debugging
level is set to a true value.
log( SCALAR )
The "log()" method will send SCALAR to STDERR by default. It
performs no processing of SCALAR and merely sends its results to
the error handle. To change your logging mechanism simply override
this method in the class as you see fit.
