pyTangoDevice version 1
Class to use a Tango device
ex :
>>> test=pyTangoDevice("tango/tangotest/1")
Now tango can access easily to the device
Read an attribute :
>>> test.short_scalar
45
Write an attribute :
>>> test.short_scalar_w=3
Execute a command :
>>> test.Init()
Execute a command with a return value :
>>> test.DevLong(1)
1
Get the current state :
>>> device.State()
PyTango.DevState.ON
--- for some use we need a function to access to atributes,
so each attribute have a set and get command
>>> test.get_double_scalar()
221.70272980813175
>>> test.set_short_scalar_w(3) for READ attribute only
--- for some use we need to wait that a device is ready (ON)
so I add a function waitStateON() to wait the DevState::ON
>>> test.waitStateON() will not work because tangotest state is UNKNOWN

Methods defined here:
- __getattr__(self, name)
- call for an attribute 'name'
ex : >>> print mydevice.name
call the function read_attribute('name').value
- __init__(self, name)
- Class to use easily a Tango device
name : device server name
- __repr__(self)
- __setattr__(self, name, arg)
- pass a value to an atribute name
ex : >>> mydevice.name=10.2
check if attribute is writable
call the function read_attribute and write_attribute
- __str__(self)
- waitStateON(self)
- function to wait the DevState::ON (DevState.ON)
of the device server
