CompositesMap¶

class lsst.daf.butler.CompositesMap(config: Union[str, ButlerConfig, CompositesConfig], *, universe: DimensionUniverse)¶

Determine whether a specific datasetType or StorageClass should be disassembled.

Parameters:	config : `str`, `ButlerConfig`, or `CompositesConfig` Configuration to control composites disassembly. universe : `DimensionUniverse` Set of all known dimensions, used to expand and validate any used in lookup keys.

Methods Summary

shouldBeDisassembled(entity, DatasetType, …) Given some choices, indicate whether the entity should be disassembled.

Methods Documentation

shouldBeDisassembled(entity: Union[DatasetRef, DatasetType, StorageClass]) → bool¶

Given some choices, indicate whether the entity should be disassembled.

Parameters:	entity : `StorageClass` or `DatasetType` or `DatasetRef` Thing to test against the configuration. The `name` property is used to determine a match. A `DatasetType` will first check its name, before checking its `StorageClass`. If there are no matches the default will be returned. If the associated `StorageClass` is not a composite, will always return `False`.
Returns:	disassemble : `bool` Returns `True` if disassembly should occur; `False` otherwise.
Raises:	ValueError The supplied argument is not understood.
