Package gavo :: Package votable :: Module paramval

Module paramval


Serialisation of python values to VOTable PARAM values.

This has two aspects:

- Guessing proper VOTable type descriptors for python values
  (use guessParamAttrsForValue)
- Serialising the python values to strings suitable for the PARAM.
  (use serializeToParam)

Classes
	PrimitiveAnnotatedColumn A stand-in for serializers.AnnotatedColumn.

Functions

guessParamAttrsForValue(pythonVal)
returns a dict of proposed attributes for a PARAM to keep pythonVal.

source code

getVOTSerializer(*args)
returns a function serializing for values of params with the attributes given.

source code

serializeToParam(param, val)
changes the VOTable PARAM param such that val is represented.

source code

getVOTParser(*args)
returns a function deserializing values in a param with datatype, arraysize, and xtype.

source code

Variables
	__package__ = `'gavo.votable'`

Function Details

guessParamAttrsForValue(pythonVal)

source code

returns a dict of proposed attributes for a PARAM to keep pythonVal.

There is, of course, quite a bit of heuristics involved. For instance, we assume sequences are homogeneous.

getVOTSerializer(*args)

source code

returns a function serializing for values of params with the attributes given.

serializeToParam(param, val)

source code

changes the VOTable PARAM param such that val is represented.

This may involve adding a null value.

getVOTParser(*args)

source code

returns a function deserializing values in a param with datatype, arraysize, and xtype.
