A packet representing a collection of normal surfaces in a 3-manifold.
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 NormalSurfaceVector class notes for details of what to do when introducing a new coordinate system.
Normal surface lists should be created using the routine enumerate().

The type of object being pointed to.
|
inherited |
Returns a detailed text representation of this object.
This text may span many lines, and should provide the user with all the information they could want. It should be human-readable, should not contain extremely long lines (which cause problems for users reading the output in a terminal), and should end with a final newline. There are no restrictions on the underlying character set.
|
inlineinherited |
Is there one or more SafePtr currently pointing to this object?
|
inherited |
Returns a short text representation of this object.
This text should be human-readable, should fit on a single line, and should not end with a newline. Where possible, it should use plain ASCII characters.
str()
.
|
inherited |
Returns a short text representation of this object using unicode characters.
Like str(), this text should be human-readable, should fit on a single line, and should not end with a newline. In addition, it may use unicode characters to make the output more pleasant to read. This string will be encoded in UTF-8.
