`Controller`

Classes

Controller

ControllerClass

Controller

class Controller(dclass, name)[source]

Bases: PoolDevice

initialize the device once in the object lifetime. Override when necessary but always call the method from your super class

Parameters:: name – device name

get_ctrl()[source]

set_ctrl(ctrl)[source]

property ctrl

delete_device()[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()[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

initialize_attribute_values()[source]: Initialize attribute values.

get_role_ids()[source]

always_executed_hook(self)[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

Raises:: DevFailed – This method does not throw exception but a redefined method can.

dev_state()[source]

Calculates and returns the device state. Called by Tango on a read state request.

Returns:: the device state

dev_status()[source]

Calculates and returns the device status. Called by Tango on a read status request.

Returns:: the device status

read_ElementList(attr)[source]

CreateElement(argin)[source]

DeleteElement(argin)[source]

get_element_names()[source]

on_controller_changed(event_src, event_type, event_value)[source]

get_dynamic_attributes()[source]

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

read_DynamicAttribute(attr)[source]

Generic read dynamic attribute. Default implementation raises NotImplementedError

Parameters:: attr – attribute to be read
Raises:: NotImplementedError

write_DynamicAttribute(attr)[source]

Generic write dynamic attribute. Default implementation raises NotImplementedError

Parameters:: attr – attribute to be written
Raises:: NotImplementedError

read_LogLevel(attr)[source]

write_LogLevel(attr)[source]

ControllerClass

class ControllerClass(name)[source]

Bases: PoolDeviceClass

class_property_list = {}: Sardana device class properties definition
