Controller

- class Controller(dclass, name)[source]
Bases:
PoolDevice- init(name)[source]
initialize the device once in the object lifetime. Override when necessary but always call the method from your super class
- Parameters:
name – device name
- property ctrl
- delete_device()[source]
Clean the device. Called during shutdown and every time the tango
Initcommand 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 tangoInitcommand is executed. Override when necessary but always call the method from your super class
- 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
- 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:
- write_DynamicAttribute(attr)[source]
Generic write dynamic attribute. Default implementation raises
NotImplementedError- Parameters:
attr – attribute to be written
- Raises:
