typedef bool(* regina::AcceptTriangulation)(NTriangulation *, void *) |
A legacy typedef that is identical to NCensus::AcceptTriangulation.
See NCensus::AcceptTriangulation for further details.
typedef std::list<NIsomorphism*> regina::NFacePairingIsoList |
A legacy typedef provided for backward compatibility only.
typedef void(* regina::UseDim2GluingPerms)(const Dim2GluingPermSearcher *, void *) |
A routine used to do arbitrary processing upon a particular set of triangle gluing permutations.
Such routines are used to process permutation sets found when running Dim2GluingPermSearcher::findAllPerms().
The first parameter passed will be a set of gluing permutations (in fact it will be of the subclass Dim2GluingPermSearcher in order to support partial searches as well as full searches). This set of gluing permutations must not be deallocated by this routine, since it may be used again later by the caller. The second parameter may contain arbitrary data as passed to either Dim2GluingPerms::findAllPerms() or the Dim2GluingPermSearcher class constructor.
Note that the first parameter passed might be null
to signal that gluing permutation generation has finished.
typedef void(* regina::UseFacePairing)(const NFacePairing *, const NFacePairingIsoList *, void *) |
A legacy typedef provided for backward compatibility only.

Constants used in the vertexStateChanged array to indicate how a partial vertex link becomes glued to itself along two of its boundary edges.
See vertexStateChanged for details.
Flags to indicate that our enumeration may (at the discretion of the enumeration algorithm) ignore certain classes of triangulations.
These flags can be combined using bitwise OR.
See the NGluingPermSearcher constructor documentation for further details on how these flags are used.
