IORegister

class IORegister(dclass, name)

Bases: PoolElementDevice

ignore_memorized_attrs_during_initialization = ('Value',)

init(name)

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_ior()

set_ior(ior)

property ior

set_write_value_to_db()

get_write_value_from_db()

delete_device()

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()

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_ior_changed(event_source, event_type, event_value)

always_executed_hook(self)

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.

get_dynamic_attributes()

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

initialize_dynamic_attributes()

Initializes this device dynamic attributes

read_Value(attr)

write_Value(attr)

is_Value_allowed(req_type)
