SYNOPSIS

9         use Pipeline::Base;
10
11         $object = Pipeline::Base->new()
12         $object->debug( 10 );
13         $object->emit("message");

DESCRIPTION

16       "Pipeline::Base" is a class that provides a basic level of
17       functionality for all classes in the Pipeline system.  Most importantly
18       it provides the construction and initialization of new objects.
19

METHODS

21       CLASS->new()
22           The "new()" method is a constructor that returns an instance of
23           receiving class.
24
25       init( LIST );
26           "init()" is called by the constructor, "new()" and is passed all of
27           its arguments in LIST.
28
29       debug( [ SCALAR ] )
30           The "debug()" method gets and sets the debug state of the OBJECT.
31           Setting it to a true value will cause messages sent to "emit()" to
32           be printed to the terminal.  If debug() is called as a class method
33           it always will return true.
34
35       emit( SCALAR )
36           "emit()" is a debugging tool.  It will cause the the SCALAR to be
37           formatted and sent to the "log()" method if the current debugging
38           level is set to a true value.
39
40       log( SCALAR )
41           The "log()" method will send SCALAR to STDERR by default.  It
42           performs no processing of SCALAR and merely sends its results to
43           the error handle.  To change your logging mechanism simply override
44           this method in the class as you see fit.
