Häufige Annahme

Mustermann.new always allocates a new pattern instance and pattern.params simply delegates to pattern.match to retrieve cached parameter hashes.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• 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.
