cachemethod#

gammapy.utils.cache.cachemethod(fn)[source]#

Decorator to cache method results on a per-instance basis using weak references.

This decorator stores cached results of method calls in a WeakKeyDictionary, ensuring that the cache is automatically cleared when the instance is garbage collected. The cache key is generated using make_key, which normalizes and hashes the method arguments to ensure consistent and order-independent caching.
