Such a packet must always be a child packet of the triangulation from which the surfaces were obtained. If this triangulation changes, the information contained in this packet will become invalid.
See the NNormalSurfaceVector class notes for details of what to do when introducing a new flavour of coordinate system.
Normal surface lists should be created using the routine enumerate(), which is new as of Regina 3.95.
Feature: Allow generating only closed surfaces.
Feature: Generate facets of the solution space representing embedded surfaces.

Determines if this packet depends upon its parent. This is true if the parent cannot be altered without invalidating or otherwise upsetting this packet.
Implements regina::NPacket. |

Enumerates all vertex normal surfaces in the given triangulation using the given flavour of coordinate system. These vertex normal surfaces will be stored in a new normal surface list. Their representations will use the smallest possible integer coordinates. The option is offered to find only embedded normal surfaces or to also include immersed and singular normal surfaces. The normal surface list that is created will be inserted as the last child of the given triangulation. This triangulation must remain the parent of this normal surface list, and must not change while this normal surface list remains in existence. If a progress manager is passed, the normal surface enumeration will take place in a new thread and this routine will return immediately. The NProgress object assigned to this progress manager is guaranteed to be of the class NProgressNumber. If no progress manager is passed, the enumeration will run in the current thread and this routine will return only when the enumeration is complete. Note that this enumeration can be extremely slow for larger triangulations.

Returns the flavour of coordinate system being used by the surfaces stored in this set. This will be one of the predefined coordinate system constants in NNormalSurfaceList.
Implements regina::NSurfaceSet. |
|
Returns the number of surfaces stored in this set.
Implements regina::NSurfaceSet. |
|
Returns the integer ID representing this type of packet. This is the same for all packets of this class.
Implements regina::NPacket. |
|
Returns an English name for this type of packet.
An example is
Implements regina::NPacket. |
|
Returns this object cast as a ShareableObject.
Generally the implementation of this routine will simply be This routine is necessary because NSurfaceSet is not of type ShareableObject; however, it is presumed that each of its derived classes will be. The aim here is to reduce the mess that could arise combining virtual multiple inheritance with the voluminous casting and recasting that takes place when working with external interfaces.
Implements regina::NSurfaceSet. |
|
Returns the surface at the requested index in this set.
Implements regina::NSurfaceSet. |
|
Returns the triangulation upon which these normal surfaces are based.
Implements regina::NSurfaceSet. |

Returns a newly created XML element reader that will read the contents of a single XML packet element. You may assume that the packet to be read is of the same type as the class in which you are implementing this routine. The XML element reader should read exactly what writeXMLPacketData() writes, and vice versa. parent represents the packet which will become the new packet's parent in the tree structure, and may be assumed to have already been read from the file. This information is for reference only, and does not need to be used. The XML element reader can either insert or not insert the new packet beneath parent in the tree structure as it pleases. Note however that parent will be 0 if the new packet is to become a tree matriarch. This routine is not actually provided for NPacket itself, but must be declared and implemented for every packet subclass that will be instantiated.
Reimplemented from regina::NPacket. |

Makes a newly allocated copy of this packet. This routine should not insert the new packet into the tree structure, clone the packet's associated tags or give the packet a label. It should also not clone any descendants of this packet. You may assume that the new packet will eventually be inserted into the tree beneath either the same parent as this packet or a clone of that parent.
Implements regina::NPacket. |
|
Returns whether this set is known to contain only embedded normal surfaces.
If it is possible that there are non-embedded surfaces in this set but it is not known whether any are actually present or not, this routine should return
Implements regina::NSurfaceSet. |
|
Reads a single packet from the specified file and returns a newly created object containing that information. You may assume that the packet to be read is of the same type as the class in which you are implementing this routine. The newly created object must also be of this type. For instance, NTriangulation::readPacket() may assume that the packet is of type NTriangulation, and must return a pointer to a newly created NTriangulation. Deallocation of the newly created packet is the responsibility of whoever calls this routine. The packet type and label may be assumed to have already been read from the file, and should not be reread. The readPacket() routine should read exactly what writePacket() writes, and vice versa. parent represents the packet which will become the new packet's parent in the tree structure, and may be assumed to have already been read from the file. This information is for reference only, and does not need to be used. This routine can either insert or not insert the new packet beneath parent in the tree structure as it pleases. Note however that parent will be 0 if the new packet is to become a tree matriarch. This routine is not actually provided for NPacket itself, but must be declared and implemented for every packet subclass that will be instantiated. Within each such subclass the function must be declared to return a pointer to an object of that subclass. For instance, NTriangulation::readPacket() must be declared to return an NTriangulation*, not simply an NPacket*. New packet types should make this routine simply return 0 since this file format is now obsolete, and older calculation engines will not understand newer packet types anyway.

Returns a newly created matrix containing the matching equations that were used to create this normal surface list. The destruction of this matrix is the responsibility of the caller of this routine. Multiple calls to this routine will result in the construction of multiple matrices. This routine in fact merely calls makeMatchingEquations() with the appropriate parameters. The format of the matrix is identical to that returned by makeMatchingEquations().
|
|
Writes the packet details to the given old-style binary file. You may assume that the packet type and label have already been written. Only the actual data stored in the packet need be written. The default implementation for this routine does nothing; new packet types should not implement this routine since this file format is now obsolete, and older calculation engines will simply skip unknown packet types when reading from binary files.
Reimplemented from regina::NPacket. |
|
Writes this object in long text format to the given output stream. The output should provided the user with all the information they could want. The output should end with a newline. The default implementation of this routine merely calls writeTextShort() and adds a newline.
Reimplemented from regina::ShareableObject. |
|
Writes this object in short text format to the given output stream. The output should fit on a single line and no newline should be written.
Implements regina::ShareableObject. |
|
Writes a chunk of XML containing the data for this packet only. You may assume that the packet opening tag (including the packet type and label) has already been written, and that all child packets followed by the corresponding packet closing tag will be written immediately after this routine is called. This routine need only write the internal data stored in this specific packet.
Implements regina::NPacket. |

Represents standard triangle-quad-oct coordinates for almost normal surfaces.
|
|
Represents edge weight coordinates for normal surfaces. This flavour is for representation only; surface vectors and lists of this flavour cannot be created. |
|
Stores whether we are only interested in embedded normal surfaces.
|

Represents face arc coordinates for normal surfaces. This flavour is for representation only; surface vectors and lists of this flavour cannot be created. |
|
Stores which flavour of coordinate system is being used by the normal surfaces in this packet.
|
|
Contains the integer ID for this packet. Each distinct packet type must have a unique ID, and this should be a positive integer. See packetregistry.h for further requirements regarding ID selection. This member is not actually provided for NPacket itself, but must be declared for every packet subclass that will be instantiated. A value need not be assigned; packetregistry.h will take care of this task when you register the packet. Reimplemented from regina::NPacket. |
