packet (SnapPea triangulation)

Description

In Regina 6.0.1 and earlier, the packet element was used to store every packet in the entire packet tree that makes up a Regina data file. This page describes how the packet element was structured when storing a SnapPea triangulation. Since Regina 7.0, each packet type has its own XML element; in particular, SnapPea triangulations are now stored using the snappeadata element.

A SnapPea triangulation packet stores a 3-manifold triangulation using SnapPea's text-based file format (instead of Regina's own native format). This is useful when working with a triangulation that originated from SnapPea or SnapPy, since it will preserve all of SnapPea's own internal data (e.g., peripheral curves and fillings).

This packet contains a single snappea element, which contains the full contents of a SnapPea data file (using SnapPea's text-based file format).

The roles played by the child tag and packet elements are described in the general packet element documentation.
