/**
 * A local interface we can use to make "header checker" objects which can be used by
 * HeaderIterators to filter results.  This really SHOULD be done with anonymous classes:
 *  * public void getHeadersByRole(final String role) {
 *     return new HeaderIterator() {
 *         public boolean checkHeader(SOAPHeaderBlock header) {
 *             ...
 *             if (role.equals(headerRole)) return true;
 *             return false;
 *         }
 *     }
 * }
 * ...but there appears to be some kind of weird problem with the JVM not correctly scoping the
 * passed "role" value in a situation like the above.  As such, we have to make Checker objects
 * instead (sigh).
