/** TripleMatcher is used to count how many Triples

* <pre>
* http://somePredicate URI http://someURI
* </pre>
* or
* <pre>
* http://somePredicate REGEXP someRegularExpression
* </pre>
*
* Which look for triples which have the specified predicate
* and an Object that matches the rest of the expression using
* the specified matching operator (URI, REGEXP etc).

* The parsing is not part of this interface, it's an implementation
