def __init__(self, items, *args): (source)

Create a group of aliases.

Parse a list of alias strings and, for each, create an appropriate alias object.

Parameters	items	Aliases. (type: `list` of `bytes`)
	args	Arguments for `AliasBase.__init__`. (type: n-`tuple` of (0) `dict` mapping `bytes` to `IDomain` provider, (1) `bytes`)

def __len__(self): (source)

Return the number of aliases in the group.

Returns The number of aliases in the group. (type: int)

def __str__(self): (source)

Build a string representation of this AliasGroup instance.

def createMessageReceiver(self): (source)

Create a message receiver for each alias and return a message receiver which will pass on a message to each of those.

Returns A message receiver which passes a message on to message receivers for each alias in the group. (type: MultiWrapper)

def resolve(self, aliasmap, memo=None): (source)

Map each of the aliases in the group to its ultimate destination.

Parameters	aliasmap	A mapping of username to alias or group of aliases. (type: `dict` mapping `bytes` to `AliasBase`)
	memo	A record of the aliases already considered in the resolution process. If provided, `memo` is modified to include this alias. (type: `None` or `dict` of `AliasBase`)
