Known Subclasses:

DatalinkCore

Basic functionality for datalink cores.

This is pulled out of the datalink core proper as it is used without the complicated service interface sometimes, e.g., by SSAP.

Method Details

completeElement(self, ctx)

source code

Overrides: base.structure.Structure.completeElement

getDatalinksResource(self, ctx, service)

source code

returns a VOTable RESOURCE element with the data links.

This does not contain the actual service definition elements, but it does contain references to them.

You must pass in a VOTable context object ctx (for the management of ids). If this is the entire content of the VOTable, use votablewrite.VOTableContext() there.
