OutputDatasetField

lsst.pipe.base.OutputDatasetField(doc, name, units, storageClass, scalar=False, check=None)

Factory function to create Config class instances of OutputDatasetConfig

This function servers as syntactic sugar for creating Configurable fields which are OutputDatasetConfig. The naming of this function violates the normal convention of a lowercase first letter in the function name, as this function is intended to sit in the same place as ConfigField classes, and consistency in declaration syntax is important.

The input arguments for this class are a combination of the arguments for ConfigField and OutputDatasetConfig. The arguments doc and check come from ConfigField, while name, units, scalar, and storageClass come from OutputDatasetConfig.

Parameters:

doc : str

Documentation string for the OutputDatasetConfig

name : str

Name of the DatasetType in the returned OutputDatasetConfig

units : iterable of str

Iterable of DataUnits for this DatasetType

scalar : bool, optional

If set to True then only a single dataset is expected on input or produced on output. In that case list of objects/DataIds will be unpacked before calling task methods, returned data is expected to contain single objects as well.

storageClass : str

Name of the StorageClass in the OutputDatasetConfig

check : callable

A callable to be called with the field value that returns False if the value is invalid.

Returns:

result : ConfigField

Instance of a ConfigField with InputDatasetConfig as a dtype
