Detailed Description

A simple handler that prints pipeline error messages to stderr, and
stops the pipeline and terminates the mainloop at EOS.  Complex
applications will need to write their own pipeline handler, but for
most simple applications this will suffice, and it's easier than
copy-and-pasting this all over the place.

Member Function Documentation

do_on_message()

def python.simplehandler.Handler.do_on_message	(		self,
			bus,
			message
	)

Add extra message handling by overriding this in your
subclass.  If this method returns True, no further message
handling is performed.  If this method returns False,
message handling continues with default cases or EOS, INFO,
WARNING and ERROR messages.

quit()

def python.simplehandler.Handler.quit	(		self,
			bus
	)

Decouple this object from the Bus object to allow the Bus'
reference count to drop to 0, and .quit() the mainloop
object.  This method is invoked by the default EOS and
ERROR message handlers.
