LookupKey¶

Representation of key that can be used to lookup information.

Look up is based on dataset type name, storage class name, dimensions.

Parameters:

namestr, optional: Primary index string for lookup. If this string looks like it represents dimensions (via dim1+dim2+dim3 syntax) the name is converted to a DimensionGraph and stored in dimensions property.
dimensionsDimensionGraph, optional: Dimensions that are relevant for lookup. Should not be specified if name is also specified.
dataIddict, optional: Keys and values from a dataId that should control lookups.
universeDimensionUniverse, optional: Set of all known dimensions, used to expand and validate name or dimensions. Required if the key represents dimensions and a full DimensionGraph is not provided.

Attributes Summary

`dataId`	Return dict of keys/values that are important for dataId lookup.
`dimensions`	Dimensions associated with lookup (`DimensionGraph`).
`name`	Primary name string to use as lookup (`str`).

Methods Summary

clone([name, dimensions, dataId])

Clone the object, overriding some options.

dataId¶

Return dict of keys/values that are important for dataId lookup.

Methods Documentation

clone(name: str | None = None, dimensions: DimensionGraph | None = None, dataId: Dict[str, Any] | None = None) → LookupKey¶

Clone the object, overriding some options.

Used to create a new instance of the object whilst updating some of it.

Parameters:

namestr, optional: Primary index string for lookup. Will override dimensions if dimensions are set.
dimensionsDimensionGraph, optional: Dimensions that are relevant for lookup. Will override name if name is already set.
dataIddict, optional: Keys and values from a dataId that should control lookups.

Returns:
