gavo.base.valuemappers.SerManager

Class SerManager

A wrapper for the serialisation of table data.

SerManager instances keep information on what values certain columns can assume and how to map them to concrete values in VOTables, HTML or ASCII.

They are constructed with a BaseTable instance.

You can additionally give:

withRanges -- ignored, going away
acquireSamples -- ignored, going away
idManager -- an object mixing in utils.IdManagerMixin. This is important

if the ids we are assigning here end up in a larger document. In that case, pass in the id manager of that larger document. Default is the SerManager itself
mfRegistry -- a map factory registry. Default is the defaltMFRegistry, which is suitable for VOTables.

Iterate over a SerManager to retrieve the annotated columns.

Instance Methods

__init__(self, table, withRanges=True, acquireSamples=True, idManager=None, mfRegistry=<gavo.utils.serializers.ValueMapperFactoryRegistry object>)
x.__init__(...) initializes x; see help(type(x)) for signature

source code

__iter__(self)

source code

getColumnByName(self, name)
returns an AnnotatedColumn element for name.

source code

getMappedValues(self)
iterates over the table's rows as dicts with mapped values.

source code

getMappedTuples(self)
iterates over the table's rows as tuples with mapped values.

Method Details

init(self, table, withRanges=True, acquireSamples=True, idManager=None, mfRegistry=<gavo.utils.serializers.ValueMapperFactoryRegistry object>)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__: (inherited documentation)

getColumnByName(self, name)

source code

returns an AnnotatedColumn element for name.

To help out in case name has gone through postgres, this will try name lowercased if it doesn't match in normal case.

This will raise a KeyError if name can't be found anyway.
