Base class for plugins that have `Param` `NameSpace` attributes.
Subclasses of `HasParam` will on one or more attributes store `NameSpace`
instances containing zero or more `Param` instances. These parameters might
describe, for example, the arguments and options a command takes, or the
attributes an LDAP entry can include, or whatever else the subclass sees
fit.
Although the interface a subclass must implement is very simple, it must
conform to a specific naming convention: if you want a namespace
``SubClass.foo``, you must define a ``Subclass.takes_foo`` attribute and a
``SubCLass.get_foo()`` method, and you may optionally define a
``SubClass.check_foo()`` method.
A quick big-picture example
===========================
Say you want the ``options`` instance attribute on your subclass to be a
`Param` `NameSpace`... then according to the enforced naming convention,
your subclass must define a ``takes_options`` attribute and a
``get_options()`` method. For example:
>>> from ipalib import Str, Int
>>> class Example(HasParam):
...
... options = None # This will be replaced with your namespace
...
... takes_options = (Str('one'), Int('two'))
...
... def get_options(self):
... return self._get_param_iterable('options')
...
>>> eg = Example()
The ``Example.takes_options`` attribute is a ``tuple`` defining the
parameters you want your ``Example.options`` namespace to contain. Your
``Example.takes_options`` attribute will be accessed via
`HasParam._get_param_iterable()`, which, among other things, enforces the
``('takes_' + name)`` naming convention. For example:
>>> eg._get_param_iterable('options')
(Str('one'), Int('two'))
The ``Example.get_options()`` method simply returns
``Example.takes_options`` by calling `HasParam._get_param_iterable()`. Your
``Example.get_options()`` method will be called via
`HasParam._filter_param_by_context()`, which, among other things, enforces
the ``('get_' + name)`` naming convention. For example:
>>> list(eg._filter_param_by_context('options'))
[Str('one'), Int('two')]
At this point, the ``eg.options`` instance attribute is still ``None``:
>>> eg.options is None
True
`HasParam._create_param_namespace()` will create the ``eg.options``
namespace from the parameters yielded by
`HasParam._filter_param_by_context()`. For example:
>>> eg._create_param_namespace('options')
>>> eg.options
NameSpace(<2 members>, sort=False)
>>> list(eg.options) # Like dict.__iter__()
['one', 'two']
Your subclass can optionally define a ``check_options()`` method to perform
sanity checks. If it exists, the ``check_options()`` method is called by
`HasParam._create_param_namespace()` with a single value, the `NameSpace`
instance it created. For example:
>>> class Example2(Example):
...
... def check_options(self, namespace):
... for param in namespace(): # Like dict.itervalues()
... if param.name == 'three':
... raise ValueError("I dislike the param 'three'")
... print ' ** Looks good! **' # Note output below
...
>>> eg = Example2()
>>> eg._create_param_namespace('options')
** Looks good! **
>>> eg.options
NameSpace(<2 members>, sort=False)
However, if we subclass again and add a `Param` named ``'three'``:
>>> class Example3(Example2):
...
... takes_options = (Str('one'), Int('two'), Str('three'))
...
>>> eg = Example3()
>>> eg._create_param_namespace('options')
Traceback (most recent call last):
...
ValueError: I dislike the param 'three'
>>> eg.options is None # eg.options was not set
True
The Devil and the details
=========================
In the above example, ``takes_options`` is a ``tuple``, but it can also be
a param spec (see `create_param()`), or a callable that returns an iterable
containing one or more param spec. Regardless of how ``takes_options`` is
defined, `HasParam._get_param_iterable()` will return a uniform iterable,
conveniently hiding the details.
The above example uses the simplest ``get_options()`` method possible, but
you could instead implement a ``get_options()`` method that would, for
example, produce (or withhold) certain parameters based on the whether
certain plugins are loaded.
Think of ``takes_options`` as declarative, a simple definition of *what*
parameters should be included in the namespace. You should only implement
a ``takes_options()`` method if a `Param` must reference attributes on your
plugin instance (for example, for validation rules); you should not use a
``takes_options()`` method to filter the parameters or add any other
procedural behaviour.
On the other hand, think of the ``get_options()`` method as imperative, a
procedure for *how* the parameters should be created and filtered. In the
example above the *how* just returns the *what* unchanged, but arbitrary
logic can be implemented in the ``get_options()`` method. For example, you
might filter certain parameters from ``takes_options`` base on some
criteria, or you might insert additional parameters provided by other
plugins.
The typical use case for using ``get_options()`` this way is to procedurally
generate the arguments and options for all the CRUD commands operating on a
specific LDAP object: the `Object` plugin defines the possible LDAP entry
attributes (as `Param`), and then the CRUD commands intelligently build
their ``args`` and ``options`` namespaces based on which attribute is the
primary key. In this way new LDAP attributes (aka parameters) can be added
to the single point of definition (the `Object` plugin), and all the
corresponding CRUD commands pick up these new parameters without requiring
modification. For an example of how this is done, see the
`ipalib.crud.Create` base class.
However, there is one type of filtering you should not implement in your
``get_options()`` method, because it's already provided at a higher level:
you should not filter parameters based on the value of ``api.env.context``
nor (preferably) on any values in ``api.env``.
`HasParam._filter_param_by_context()` already does this by calling
`Param.use_in_context()` for each parameter. Although the base
`Param.use_in_context()` implementation makes a decision solely on the value
of ``api.env.context``, subclasses can override this with implementations
that consider arbitrary ``api.env`` values.

Return an iterable of params defined by the attribute named ``name``.
A sequence of params can be defined one of three ways: as a ``tuple``;
as a callable that returns an iterable; or as a param spec (a `Param` or
``str`` instance). This method returns a uniform iterable regardless of
how the param sequence was defined.
For example, when defined with a tuple:
>>> class ByTuple(HasParam):
... takes_args = (Param('foo'), Param('bar'))
...
>>> by_tuple = ByTuple()
>>> list(by_tuple._get_param_iterable('args'))
[Param('foo'), Param('bar')]
Or you can define your param sequence with a callable when you need to
reference attributes on your plugin instance (for validation rules,
etc.). For example:
>>> class ByCallable(HasParam):
... def takes_args(self):
... yield Param('foo', self.validate_foo)
... yield Param('bar', self.validate_bar)
...
... def validate_foo(self, _, value, **kw):
... if value != 'Foo':
... return _("must be 'Foo'")
...
... def validate_bar(self, _, value, **kw):
... if value != 'Bar':
... return _("must be 'Bar'")
...
>>> by_callable = ByCallable()
>>> list(by_callable._get_param_iterable('args'))
[Param('foo', validate_foo), Param('bar', validate_bar)]
Lastly, as a convenience for when a param sequence contains a single
param, your defining attribute may a param spec (either a `Param`
or an ``str`` instance). For example:
>>> class BySpec(HasParam):
... takes_args = Param('foo')
... takes_options = 'bar?'
...
>>> by_spec = BySpec()
>>> list(by_spec._get_param_iterable('args'))
[Param('foo')]
>>> list(by_spec._get_param_iterable('options'))
['bar?']
For information on how an ``str`` param spec is interpreted, see the
`create_param()` and `parse_param_spec()` functions in the
`ipalib.parameters` module.
Also see `HasParam._filter_param_by_context()`.

This method creates the ``args``, ``options``, and ``params``

subclasses (like `crud.Add`) might need to access other plugins
loaded in self.api to determine what their custom `Command.get_args`

Generic output method. Prints values the output argument according
to their type and self.output.
Entry attributes are labeled and printed in the order specified in
self.output_params. Attributes that aren't present in
self.output_params are not printed unless the command was invokend
with the --all option. Attribute labelling is disabled if the --raw
option was given.
Subclasses can override this method, if custom output is needed.

Dispatch to forward() or execute() based on ``server`` option.
When running in a client context, this command is executed remotely if
``options['server']`` is true; otherwise it is executed locally.
When running in a server context, this command is always executed
locally and the value of ``options['server']`` is ignored.

Base class implementing the attribute-to-object association.
`Attribute` plugins are associated with an `Object` plugin to group
a common set of commands that operate on a common set of parameters.
The association between attribute and object is done using a simple
naming convention: the first part of the plugin class name (up to the
first underscore) is the object name, and rest is the attribute name,
as this table shows:
=============== =========== ==============
Class name Object name Attribute name
=============== =========== ==============
noun_verb noun verb
user_add user add
user_first_name user first_name
=============== =========== ==============
For example:
>>> class user_add(Attribute):
... pass
...
>>> instance = user_add()
>>> instance.obj_name
'user'
>>> instance.attr_name
'add'
In practice the `Attribute` class is not used directly, but rather is
only the base class for the `Method` and `Property` classes. Also see
the `Object` class.

A command with an associated object.
A `Method` plugin must have a corresponding `Object` plugin. The
association between object and method is done through a simple naming
convention: the first part of the method name (up to the first under
score) is the object name, as the examples in this table show:
============= =========== ==============
Method name Object name Attribute name
============= =========== ==============
user_add user add
noun_verb noun verb
door_open_now door open_now
============= =========== ==============
There are three different places a method can be accessed. For example,
say you created a `Method` plugin and its corresponding `Object` plugin
like this:
>>> from ipalib import create_api
>>> api = create_api()
>>> class user_add(Method):
... def run(self):
... return dict(result='Added the user!')
...
>>> class user(Object):
... pass
...
>>> api.register(user_add)
>>> api.register(user)
>>> api.finalize()
First, the ``user_add`` plugin can be accessed through the ``api.Method``
namespace:
>>> list(api.Method)
['user_add']
>>> api.Method.user_add() # Will call user_add.run()
{'result': 'Added the user!'}
Second, because `Method` is a subclass of `Command`, the ``user_add``
plugin can also be accessed through the ``api.Command`` namespace:
>>> list(api.Command)
['user_add']
>>> api.Command.user_add() # Will call user_add.run()
{'result': 'Added the user!'}
And third, ``user_add`` can be accessed as an attribute on the ``user``
`Object`:
>>> list(api.Object)
['user']
>>> list(api.Object.user.methods)
['add']
>>> api.Object.user.methods.add() # Will call user_add.run()
{'result': 'Added the user!'}
The `Attribute` base class implements the naming convention for the
attribute-to-object association. Also see the `Object` and the
`Property` classes.

All plugins that subclass from `Updater` will be automatically available
as a server update function.
Plugins that subclass from Updater are registered in the ``api.Updater``
namespace. For example:
