PseudoCounter¶

-
class
PseudoCounter
(dclass, name)[source]¶ Bases:
sardana.tango.pool.PoolDevice.PoolExpChannelDevice
-
init
(name)[source]¶ initialize the device once in the object lifetime. Override when necessary but always call the method from your super class
:param
str
name: device name
-
pseudo_counter
¶
-
delete_device
(**kwargs)[source]¶ Clean the device. Called during shutdown and every time the tango
Init
command is executed. Override when necessary but always call the method from your super class
-
init_device
(**kwargs)[source]¶ Initialize the device. Called during startup after
init()
and every time the tangoInit
command is executed. Override when necessary but always call the method from your super class
-
always_executed_hook
(self) → None[source]¶ - Hook method. Default method to implement an action necessary on a device before any command is executed. This method can be redefined in sub-classes in case of the default behaviour does not fullfill the needs
Parameters : None Return : None
Throws : DevFailed This method does not throw exception but a redefined method can.
-
read_attr_hardware
(self, attr_list) → None[source]¶ - Read the hardware to return attribute value(s). Default method to implement an action necessary on a device to read the hardware involved in a a read attribute CORBA call. This method must be redefined in sub-classes in order to support attribute reading
- Parameters :
- attr_list : (sequence<int>) list of indices in the device object attribute vector
- of an attribute to be read.
Return : None
Throws : DevFailed This method does not throw exception but a redefined method can.
-
get_dynamic_attributes
()[source]¶ Override of
PoolDevice.get_dynamic_attributes
. Returns the standard dynamic and fully dynamic attributes for this device. The return is a tuple of two dictionaries:- standard attributes: caseless dictionary with key being the attribute name and value is a tuple of attribute name(str), tango information, attribute information
- dynamic attributes: caseless dictionary with key being the attribute name and value is a tuple of attribute name(str), tango information, attribute information
- tango information
- seq<
CmdArgType
,AttrDataFormat
,AttrWriteType
> - attribute information
- attribute information as returned by the sardana controller
Returns: the standard dynamic and fully dynamic attributes Return type: seq< CaselessDict
