ArchiveAccessRequiredError

exception lsst.images.serialization.ArchiveAccessRequiredError

Bases: RuntimeError

Exception raised when a deserialization needs data from the file.

Raised by all data-access methods of DetachedArchive, signaling that the requested object cannot be deserialized from the JSON tree alone.

Notes

This deliberately does not inherit from ArchiveReadError: it signals that a live archive is required rather than that an archive is corrupt, and it must not be swallowed by except ArchiveReadError handlers.
