/**
* Determines if the input object matches some criteria.
*
* <p>All predicate implementations are expected to:
* <ul>
* <li>Provide stable results such that for any {@code t} the result of two
* {@code eval} operations are always equivalent. ie.<pre>
* boolean one = predicate.test(a);
* boolean two = predicate.test(a);
*
* assert one == two;
* </pre></li>
* <li>Equivalent input objects should map to equivalent output objects. ie.<pre>
* assert a.equals(b); // a and b are equivalent
*
* boolean x = predicate.test(a);
* boolean y = predicate.test(ab;
*
* assert x == y; // their test results should be the same.
* </pre></li>
* <li>The predicate should not modify the input object in any way that would
* change the evaluation.</li>
* <li>When used for aggregate operations upon many elements predicates
* should not assume that the {@code test} operation will be called upon
* elements in any specific order.</li>
* </ul>
*
* @param <T> the type of input objects provided to {@code test}.
