One can decide to cache method information using as key a concatenation of method name + signature, but the cost of concatenation is very high, while hashmap access is fast. Ternary trees avoid string concatenation, and result to be 10x faster than concatenation + hashmap. However, the signature of a standard TernaryTree would be <code>Object get(Object[] key)</code> and <code>void put(Object[] key, Object value)</code>. Unfortunately normalizing method name + signature into a single array is also very expensive. <br> This version leaves method name and signature separated to have the fastest access possible to method information.
