KeyedDataSelectorAction

class lsst.analysis.tools.actions.keyedData.KeyedDataSelectorAction(*args, **kw)

Bases: KeyedDataAction

Extract Vector specified by vectorKeys from input KeyedData and optionally apply selectors to down select extracted vectors.

Note this action will not work with keyed scalars, see getInputSchema for expected schema.

Attributes Summary

selectors	Selectors for selecting rows, will be AND together (ConfigurableActionStructField)
vectorKeys	Keys to extract from KeyedData and return (List, default [])

Methods Summary

__call__(data, **kwargs)	Call self as a function.
getInputSchema()	Return the schema an AnalysisAction expects to be present in the arguments supplied to the __call__ method.
getOutputSchema()	Return the schema an AnalysisAction will produce, if the __call__ method returns KeyedData, otherwise this may return None.

Methods Documentation

__call__(data: MutableMapping[str, ndarray[Any, dtype[_ScalarType_co]] | Scalar | HealSparseMap | Tensor | Mapping], **kwargs) → MutableMapping[str, ndarray[Any, dtype[_ScalarType_co]] | Scalar | HealSparseMap | Tensor | Mapping]

Call self as a function.

getInputSchema() → Mapping]]]

Return the schema an AnalysisAction expects to be present in the arguments supplied to the __call__ method.

Returns:

resultKeyedDataSchema

The schema this action requires to be present when calling this action, keys are unformatted.

getOutputSchema() → Mapping]]]

Return the schema an AnalysisAction will produce, if the __call__ method returns KeyedData, otherwise this may return None.

Returns:

resultKeyedDataSchema or None

The schema this action will produce when returning from call. This will be unformatted if any templates are present. Should return None if action does not return KeyedData.
