class lsst.daf.butler.registry.interfaces.DatabaseDimensionOverlapStorage¶
- Bases: - abc.ABC- A base class for objects that manage overlaps between a pair of database-backed dimensions. - Attributes Summary - elements- The pair of elements whose overlaps this object manages. - Methods Summary - digestTables()- Return tables used for schema digest. - initialize(db, elementStorage, …)- Construct an instance of this class using a standardized interface. - Attributes Documentation - 
elements¶
- The pair of elements whose overlaps this object manages. - The order of elements is the same as their ordering within the - DimensionUniverse.

classmethod initialize(db: Database, elementStorage: tuple[DatabaseDimensionRecordStorage, DatabaseDimensionRecordStorage], governorStorage: tuple[GovernorDimensionRecordStorage, GovernorDimensionRecordStorage], context: StaticTablesContext | None = None) → DatabaseDimensionOverlapStorage¶
- Construct an instance of this class using a standardized interface. - Parameters: - db : Database
- Interface to the underlying database engine and namespace. 
- elementStorage : tuple[DatabaseDimensionRecordStorage]
- Storage objects for the elements this object will related. 
- governorStorage : tuple[GovernorDimensionRecordStorage]
- Storage objects for the governor dimensions of the elements this object will related. 
- context : StaticTablesContext, optional
- If provided, an object to use to create any new tables. If not provided, - db.ensureTableExistsshould be used instead.
 - Returns: - storage : DatabaseDimensionOverlapStorage
- A new - DatabaseDimensionOverlapStoragesubclass instance.
