Inheritance diagram of TwoDExpChannel
class TwoDExpChannel(dclass, name)[source]

Bases: sardana.tango.pool.PoolDevice.PoolElementDevice

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

get_twod()[source]
set_twod(twod)[source]
twod
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 tango Init command is executed. Override when necessary but always call the method from your super class

on_twod_changed(event_source, event_type, event_value)[source]
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, CaselessDict>
read_Value(attr)[source]
