## Classes

### *class* **Action**

Action callback.

This class makes it easy to create and register action callbacks by sub-classing it and implementing cb\_action in the derived class.

```python
Action(daemon, actionpoint, log=None, init_args=None)
```

Initialize this object.

The 'daemon' argument should be a Daemon instance. 'actionpoint' is the name of the tailf:actionpoint to manage. 'log' can be any log object, and if not set the Daemon logger will be used. 'init\_args' may be any object that will be passed into init() when this object is constructed. Lastly, the low-level function dp.register\_action\_cbs() will be called.

When using this class together with ncs.application.Application there is no need to manually initialize this object as it is done by the Application.register\_action() method.

Arguments:

* daemon -- Daemon instance (dp.Daemon)
* actionpoint -- actionpoint name (str)
* log -- logging object (optional)
* init\_args -- additional arguments (optional)

Members:

<details>

<summary>action(...)</summary>

Static method:

```python
action(fn)
```

Decorator for the cb\_action callback.

Only use this decorator for actions of tailf:action type.

Using this decorator alters the signature of the cb\_action callback and passes in maagic.Node objects for input and output action data.

Example of a decorated cb\_action:

```
@Action.action
def cb_action(self, uinfo, name, kp, input, output, trans):
    pass
```

Callback arguments:

* uinfo -- a UserInfo object
* name -- the tailf:action name (string)
* kp -- the keypath of the action (HKeypathRef)
* input -- input node (maagic.Node)
* output -- output node (maagic.Node)
* trans -- read only transaction, same as action transaction if executed with an action context (maapi.Transaction)

</details>

<details>

<summary>cb_init(...)</summary>

Method:

```python
cb_init(self, uinfo)
```

The cb\_init callback must always be implemented.

This default implementation will associate a new worker socket with this callback.

</details>

<details>

<summary>init(...)</summary>

Method:

```python
init(self, init_args)
```

Custom initialization.

When registering an action using ncs.application.Application this method will be called with the 'init\_args' passed into the register\_action() function.

</details>

<details>

<summary>rpc(...)</summary>

Static method:

```python
rpc(fn)
```

Decorator for the cb\_action callback.

Only use this decorator for rpc:s.

Using this decorator alters the signature of the cb\_action callback and passes in maagic.Node objects for input and output action data.

Example of a decorated cb\_action:

```
@Action.rpc
def cb_action(self, uinfo, name, input, output):
    pass
```

Callback arguments:

* uinfo -- a UserInfo object
* name -- the rpc name (string)
* input -- input node (maagic.Node)
* output -- output node (maagic.Node)

</details>

<details>

<summary>start(...)</summary>

Method:

```python
start(self)
```

Custom actionpoint start triggered when Python VM starts up.

</details>

<details>

<summary>stop(...)</summary>

Method:

```python
stop(self)
```

Custom actionpoint stop triggered when Python VM shuts down.

</details>

### *class* **Daemon**

Manage a data provider connection towards ConfD/NCS.

```python
Daemon(name, log=None, ip='127.0.0.1', port=4569, path=None, state_mgr=None)
```

Initialize a Daemon object.

The 'name' argument should be unique. It will show up in the CLI and in error messages. All other arguments are optional. Argument 'log' can be any log object, and if not set the standard logging mechanism will be used. Set 'ip' and 'port' to where your Confd/NCS server is. 'path' is a filename to a unix domain socket to be used in place of 'ip' and 'port'. If 'path' is provided, 'ip' and 'port' arguments are ignored.

Daemon supports automatic restarting in case of error if a state manager is provided using the state\_mgr parameter.

Members:

<details>

<summary>INIT_RETRY_INTERVAL_S</summary>

```python
INIT_RETRY_INTERVAL_S = 1
```

</details>

<details>

<summary>ctx(...)</summary>

Method:

```python
ctx(self)
```

Return the daemon context.

</details>

<details>

<summary>daemon</summary>

A boolean value indicating whether this thread is a daemon thread.

This must be set before start() is called, otherwise RuntimeError is raised. Its initial value is inherited from the creating thread; the main thread is not a daemon thread and therefore all threads created in the main thread default to daemon = False.

The entire Python program exits when only daemon threads are left.

</details>

<details>

<summary>finish(...)</summary>

Method:

```python
finish(self)
```

Stop the daemon thread.

</details>

<details>

<summary>getName(...)</summary>

Method:

```python
getName(self)
```

Return a string used for identification purposes only.

This method is deprecated, use the name attribute instead.

</details>

<details>

<summary>ident</summary>

*Readonly property*

Thread identifier of this thread or None if it has not been started.

This is a nonzero integer. See the get\_ident() function. Thread identifiers may be recycled when a thread exits and another thread is created. The identifier is available even after the thread has exited.

</details>

<details>

<summary>ip(...)</summary>

Method:

```python
ip(self)
```

Return the ip address.

</details>

<details>

<summary>isDaemon(...)</summary>

Method:

```python
isDaemon(self)
```

Return whether this thread is a daemon.

This method is deprecated, use the daemon attribute instead.

</details>

<details>

<summary>is_alive(...)</summary>

Method:

```python
is_alive(self)
```

Return whether the thread is alive.

This method returns True just before the run() method starts until just after the run() method terminates. See also the module function enumerate().

</details>

<details>

<summary>join(...)</summary>

Method:

```python
join(self, timeout=None)
```

Wait until the thread terminates.

This blocks the calling thread until the thread whose join() method is called terminates -- either normally or through an unhandled exception or until the optional timeout occurs.

When the timeout argument is present and not None, it should be a floating-point number specifying a timeout for the operation in seconds (or fractions thereof). As join() always returns None, you must call is\_alive() after join() to decide whether a timeout happened -- if the thread is still alive, the join() call timed out.

When the timeout argument is not present or None, the operation will block until the thread terminates.

A thread can be join()ed many times.

join() raises a RuntimeError if an attempt is made to join the current thread as that would cause a deadlock. It is also an error to join() a thread before it has been started and attempts to do so raises the same exception.

</details>

<details>

<summary>load_schemas(...)</summary>

Method:

```python
load_schemas(self)
```

Load schema information into the process memory.

</details>

<details>

<summary>name</summary>

A string used for identification purposes only.

It has no semantics. Multiple threads may be given the same name. The initial name is set by the constructor.

</details>

<details>

<summary>native_id</summary>

*Readonly property*

Native integral thread ID of this thread, or None if it has not been started.

This is a non-negative integer. See the get\_native\_id() function. This represents the Thread ID as reported by the kernel.

</details>

<details>

<summary>path(...)</summary>

Method:

```python
path(self)
```

Return the unix domain socket path.

</details>

<details>

<summary>port(...)</summary>

Method:

```python
port(self)
```

Return the port.

</details>

<details>

<summary>register_trans_cb(...)</summary>

Method:

```python
register_trans_cb(self, trans_cb_cls=<class 'ncs.dp.TransactionCallback'>)
```

</details>

<details>

<summary>run(...)</summary>

Method:

```python
run(self)
```

Daemon thread processing loop.

Don't call this method explicitly. It handles reading of control and worker sockets and notifying ConfD/NCS that it should continue processing by calling the low-level function dp.fd\_ready(). If the connection towards ConfD/NCS is broken or if finish() is explicitly called, this function (and the thread) will end.

</details>

<details>

<summary>setDaemon(...)</summary>

Method:

```python
setDaemon(self, daemonic)
```

Set whether this thread is a daemon.

This method is deprecated, use the .daemon property instead.

```

Set the name string for this thread.

This method is deprecated, use the name attribute instead.

</details>

<details>

<summary>start(...)</summary>

Method:

```python
start(self)
```

Start daemon work thread.

After registering any callbacks (action, services and such), call this function to start processing. The low-level function dp.register\_done() will be called before the thread is started.
