*
* <pre>
* IntDoubleProcedure condition = new IntDoubleProcedure() { // match even keys only
* public boolean apply(int key, double value) { return key%2==0; }

* keys = (8,7,6), values = (1,2,2) --> keyList = (6,8), valueList = (2,1)</tt>
* </pre>
*
* @param condition the condition to be matched. Takes the current key as first and the current
* value as second argument.
* @param keyList the list to be filled with keys, can have any size.
* @param valueList the list to be filled with values, can have any size.
