/// Interface to the server access control lists
|
|
///
|
|
/// This interface focuses specifically on the state event type
|
|
/// `m.room.server_acl` which allows for access control at server scope. This
|
|
/// is necessary because access controls via `m.room.member` operate at the
|
|
/// scope of individual `state_key` cells in the room state, thus lacking the
|
|
/// ability to assert control over multiple cells and those which do not yet
|
|
/// exist.
|
|
///
|
|
/// Primary use of this interface is with operator() which returns true if
|
|
/// the server is permitted by the room's ACL and false if denied. This is
|
|
/// determined by the ACL event content only. Exceptions are not intended to be
|
|
/// thrown. The conf items resident in this class do not actually affect the
|
|
/// results of the member functions; they are for users to determine how/if
|
|
/// to invoke this interface.
|
|
