_extractKeyValue()

lsst.pipe.tasks.selectImages._extractKeyValue ( dataList, keys = None )

protected

Extract the keys and values from a list of dataIds.

The input dataList is a list of objects that have 'dataId' members.
This allows it to be used for both a list of data references and a
list of ExposureInfo.

Parameters
----------
dataList : `Unknown`
keys : `Unknown`

Returns
-------
keys : `Unknown`
values : `Unknown`

Raises
------
RuntimeError
    Raised if DataId keys are inconsistent.
