A dictionary whose keys are contact handles and whose values are aliases. A mapping from the handle representing the contact to the new alias Signal emitted when a contact's alias (or that of the user) is changed.

The aliases of contacts on this connection may be changed by the user of the service, not just by the contacts themselves. This is the case on Jabber, for instance.

It is possible that aliases can be changed by the contacts too - which alias takes precedence is not defined by this specification, and depends on the server and/or connection manager implementation.

This flag only applies to the aliases of "globally valid" contact handles. At this time, clients should not expect to be able to change the aliases corresponding to any channel-specific handles. If this becomes possible in future, a new flag will be defined.

A bitwise OR of flags from ConnectionAliasFlags detailing the behaviour of aliases on this connection. An array of handles representing contacts A list of aliases in the same order as the contact handles Request the value of several contacts' aliases at once.

A dictionary mapping integer handles of contacts to strings of the new alias to set. Request that the alias of the given contact be changed. Success will be indicated by emitting an AliasesChanged signal. On connections where the CONNECTION_ALIAS_FLAG_USER_SET flag is not set, this method will only ever succeed if the contact is the user's own handle (as returned by the Connection.SelfHandle property).

The contact's alias. This SHOULD only return cached aliases, falling back on the contact identifier (i.e. the string corresponding to the handle) if none is present. Also if there was no cached alias, a request SHOULD be started of which the result is later signalled by AliasesChanged.

An interface on connections to support protocols where contacts have an alias which they can change at will. Provides a method for the user to set their own alias, and a signal which should be emitted when a contact's alias is changed or first discovered.

On connections where the user is allowed to set aliases for contacts and store them on the server, the AliasFlags property will have the CONNECTION_ALIAS_FLAG_USER_SET flag set, and the SetAliases method may be called on contact handles other than the user themselves.

Aliases are intended to be used as the main displayed name for the contact, where available.
