TransportUtils.i3
The
TransportUtils interface reveals methods of Transport.Ts
and Transport.Locations which are useful for management and
debugging tools.
INTERFACEThe callTransportUtils ; IMPORT Transport; REVEAL Transport.T <: Public; Transport.Location <: LocationP; TYPE Public = Transport.Public OBJECT METHODS enumerateLocs (p: EnumProc; cl: REFANY := NIL); END; EnumProc = PROCEDURE (loc: Transport.Location; cl: REFANY): BOOLEAN; LocationP = Transport.LocationP OBJECT METHODS getInfo (): TEXT; getEp (): Transport.Endpoint; END; END TransportUtils.
tr.enumerateLocs (p, cl) should invoke p (loc, cl) for
each live loc: Location owned by tr. The enumeration should
terminate after the first invocation of p which returns TRUE.
The method loc.getInfo should return a TEXT suitable for
presentation to a human which identifies the location amongst those
managed by the transport.
The method loc.getEp should return a Transport.Endpoint e
such that loc = tr.fromEndpoint (e).
