<div class="block">Specialized ternary tree for method metadata information. <p>
In JMX methods are referred to with the method name and the String[] representing the signature.
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.
See <a href="http://www.ddj.com/documents/s=921/ddj9804a/9804a.htm">here</a> for further information
on TernaryTrees.</div>
