diplomat.processing.Config

class diplomat.processing.Config(*args, **kwargs)

Bases: UserDict

Represents a configuration of settings. Is a dictionary with support for attribute style access of keys, and also allows for a backing dictionary, which can control what values are allowed to be stored in this configuration.

__init__(*args, **kwargs)

Create a new configuration dictionary:

Parameters:

• args – Only accepts 2 non-keyword arguments, the data, and a backing dictionary. See set_backing for more info.

• kwargs – Optional, additional keys and values to add to the dictionary.

Methods

__init__(*args, **kwargs)	Create a new configuration dictionary:
clear()
copy()
extract(data)
fromkeys(iterable[, value])
get(k[,d])
items()
keys()
pop(k[,d])	If key is not found, d is returned if given, otherwise KeyError is raised.
popitem()	as a 2-tuple; but raise KeyError if D is empty.
set_backing(back_dict)	Set the backing dictionary for this config object.
setdefault(k[,d])
update([E, ]**F)	If E present and has a .keys() method, does: for k in E.keys(): D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v
values()

clear() → None.  Remove all items from D.

get(k[, d]) → D[k] if k in D, else d.  d defaults to None.

items() → a set-like object providing a view on D's items

keys() → a set-like object providing a view on D's keys

pop(k[, d]) → v, remove specified key and return the corresponding value.

If key is not found, d is returned if given, otherwise KeyError is raised.

popitem() → (k, v), remove and return some (key, value) pair

as a 2-tuple; but raise KeyError if D is empty.

set_backing(back_dict: Dict[str, Tuple[T, TypeCaster[T], str]])

Set the backing dictionary for this config object.

Parameters:

back_dict –

A dictionary of strings (key names) to length 3 tuples. The tuples contain the following values in order:

• E: The default value for this setting.

• TypeCaster[E]: A casting function, to convert or check passed values are of the right type.

• str: The description of this setting, not used here…

setdefault(k[, d]) → D.get(k,d), also set D[k]=d if k not in D

update([E, ]**F) → None.  Update D from mapping/iterable E and F.

If E present and has a .keys() method, does: for k in E.keys(): D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v

values() → an object providing a view on D's values
