Package gavo :: Package base :: Module valuemappers

Module valuemappers

Serialising table rows.

The main class in this module is the SerManager, which knows about a target table and figures out how to turn the values in the table rows into strings.

This is used by formats.votablewrite and the HTML table serialisation.

utils.serializers has once been a part of this module. To save migration effort, for now it reproduces that module's interface.

Classes
	SerManager A wrapper for the serialisation of table data.
	VOTNameMaker A class for generating db-unique names from VOTable fields.
