public final class Team
extends TeamHandle

Peer object for a TeamBackEnd. An instance of a Team is created inside each team to contain that team's local data. Specifically, this class keeps track of the cross-team references coming from its team. Team objects are never created directly, they are created implicitly as part of 'Team.create()'.

The association with the TeamBackEnd in the kernel team is implicit (through TeamBackEnd.getCurrentTeam()).

Because this class extends TeamHandle, it is importable.
