Ce que l'on suppose souvent
Mustermann.new always allocates a new pattern instance and pattern.params simply delegates to pattern.match to retrieve cached parameter hashes.
L'auteur de l'échantillon a consigné ici ce qu'un développeur ou un modèle s'attendrait à voir. Le contrat ci-dessous est ce qui s'est réellement exécuté.
Contrat
- Mustermann.new returns the identical cached pattern instance for matching strings and options via WeakMap memoization rather than allocating a new pattern object each time.
- Mustermann.new with different options creates and caches a distinct pattern instance.
- pattern.match caches Mustermann::Match objects so consecutive calls with the same path return the identical memoized Match instance and cached params hash.
- pattern.params bypasses Match allocation and match caching, returning a newly allocated Hash directly from regexp named captures.
- Mustermann.new with cache: false disables Match caching, returning a new Mustermann::Match instance on each match call.
- Mustermann.new with a custom cache hash routes cached Match objects into the caller-provided hash table.
- Composite pattern operators retain memoization so unioning identical patterns returns the same composite instance.
