The following example shows how the on_stop() function of a derived class invodes the on_stop() function of the parent class.
#!/usr/bin/env python # from sardana.macroserver.macro import Macro, Type import time import PyTango class parentClass(Macro): def say( self): self.output( "parentClass.say Hello ") return def on_stop( self): self.output( "parentClass.on_stop") class derivedClass( parentClass): """prints a string""" param_def = [ [ "text", Type.String, None, "some text" ], ] def on_stop( self): self.output( "derivedClass.on_stop") # parentClass.on_stop( self) super( derivedClass, self).on_stop() def run(self, text): self.say() timer = PyTango.DeviceProxy( "p21/dgg2/exp.01") self.output( "waiting for ctrl-c") timer.SampleTime = 0.5 for n in range(20): self.output( "still waiting") timer.StartAndWaitForTimer()
