Method Details

[hide private]

init(self, args)
(Constructor)*

source code

Initialise setting the allowed type or types for keys and items

Parameters:

args (tuple) - two arguments: the first is a callable which filters for permissable keys in this dict, the second sets the type or list of types permissable for items in this dict

_verifyKeyValPair(self, key, val)

source code

Check given key value pair and return False if they should be filtered out. Filter functions may also raise an exception if they wish to abort completely

Parameters:

key (basestring) - dict key to check
val (any) - value to check

setitem(self, key, val)
(Index assignment operator)

source code

Enforce type checking when setting new items

Parameters:

key (any) - key for item to set
val (any) - value to set for this key

getitem(self, key)
(Indexing operator)

source code

Provide implementation for getting items

Parameters:

key (any) - key for item to retrieve

Returns: any

value for input key

get(self, key, *arg)

source code

Provide implementation of get item with default

Parameters:

key (any) - key for item to retrieve
arg (tuple) - use to set a default argument
