NetworkTypeaheadContext provides the information about the connections of a member (see {@link #getSource()}). Given this context, a downstream network typeahead can search for entities or activities within the first degree network connections of the specified member.
NetworkTypeaheadContext defines a mapping from U
to U
(users to users). When a context is sent to a downstream network typeahead, which specifies a mapping from U
to E
(users to entities), network entities E
associated with the first degree connections of the specified member are searched.
