RegistryResource

class pyvo.registry.regtap.RegistryResource(results, index)

Bases: pyvo.dal.query.Record

Methods Documentation

describe(verbose=False, width=78, file=None)

Print a summary description of this resource.

Parameters:

verbose : bool

If false (default), only user-oriented information is printed; if true, additional information will be printed as well.

width : int

Format the description with given character-width.

out : writable file-like object

If provided, write information to this output stream. Otherwise, it is written to standard out.

search(*args, **keys)

assuming this resource refers to a searchable service, execute a search against the resource. This is equivalent to:

self.to_service().search(*args, **keys)

The arguments provided should be appropriate for the service that the DAL service type would expect. See the documentation for the appropriate service type:

Service type	Use the argument syntax for
catalog	pyvo.dal.scs.SCSService.search()
image	pyvo.dal.sia.SIAService.search()
spectrum	pyvo.dal.ssa.SSAService.search()
line	pyvo.dal.sla.SLAService.search()
database	not yet supported

Raises:

RuntimeError

if the resource does not describe a searchable service.
