A VcExecutor returning a Tango attribute

This is virtual counter that returns the value of an attribute:

 
#!/usr/bin/env python

import PyTango

class VC:
	def __init__(self):
		print( " VC.init")
		self.proxies = []
#		self.proxies.append( PyTango.DeviceProxy( "haso107klx:10000/p09/counter/exp.01"))
		self.proxies.append( PyTango.DeviceProxy( "p09/counter/exp.01"))
	#
	# dev_state
	#
	def dev_state( self):
		return self.proxies[0].State()
	#
	# Counts
	#
	def read_Counts( self):
		print( "vc_attribute:: read-counts ")
		return self.proxies[0].Counts

	def write_Counts( self, argin):
		return 1
	#
	# reset
	#
	def Reset(self):
		#print( "vc_attribute:: resetting %s " % self.proxies[0].name())
		#self.proxies[0].Reset()
		return True

The corresponding entry in online.xml is:

Notice that this device was named 'exp_xattr' because it should appear in the list of counters behind, e.g., exp_c32.
