Pipeline::Base(3)     User Contributed Perl Documentation    Pipeline::Base(3)

       Pipeline::Base -	base class for all classes in Pipeline distribution

	 use Pipeline::Base;

	 $object = Pipeline::Base->new()
	 $object->debug( 10 );

       "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.

	   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.
