/**
 * The standard interface that provides the framework for all
 * <code>FilteredRowSet</code> objects to describe their filters.
 *
 * <h2>1.0 Background</h2>
 * The <code>Predicate</code> interface is a standard interface that
 * applications can implement to define the filter they wish to apply to a
 * a <code>FilteredRowSet</code> object. A <code>FilteredRowSet</code>
 * object consumes implementations of this interface and enforces the
 * constraints defined in the implementation of the method <code>evaluate</code>.
 * A <code>FilteredRowSet</code> object enforces the filter constraints in a
 * bi-directional manner: It outputs only rows that are within
 * the constraints of the filter; and conversely, it inserts, modifies, or updates
 * only rows that are within the constraints of the filter.
 *
 * <h2>2.0 Implementation Guidelines</h2>
 * In order to supply a predicate for the <code>FilteredRowSet</code>.
 * this interface must be implemented.  At this time, the JDBC RowSet
 * Implementations (JSR-114) does not specify any standard filters definitions.
 * By specifying a standard means and mechanism for a range of filters to be
 * defined and deployed with both the reference and vendor implementations
 * of the <code>FilteredRowSet</code> interface, this allows for a flexible
 * and application motivated implementations of <code>Predicate</code> to emerge.
 * <p>
 * A sample implementation would look something like this:
 * <pre>{@code
 *    public class Range implements Predicate {
 *
 *       private int[] lo;
 *       private int[] hi;
 *       private int[] idx;
 *
 *       public Range(int[] lo, int[] hi, int[] idx) {
 *          this.lo = lo;
 *          this.hi = hi;
 *          this.idx = idx;
 *       }
 *
 *      public boolean evaluate(RowSet rs) {
 *
 *          // Check the present row determine if it lies
 *          // within the filtering criteria.
 *
 *          for (int i = 0; i < idx.length; i++) {
 *             int value;
 *             try {
 *                 value = (Integer) rs.getObject(idx[i]);
 *             } catch (SQLException ex) {
 *                 Logger.getLogger(Range.class.getName()).log(Level.SEVERE, null, ex);
 *                 return false;
 *             }
 *
 *             if (value < lo[i] && value > hi[i]) {
 *                 // outside of filter constraints
 *                 return false;
 *             }
 *         }
 *         // Within filter constraints
 *        return true;
 *      }
 *   }
 * }</pre>
 * <P>
 * The example above implements a simple range predicate. Note, that
 * implementations should but are not required to provide <code>String</code>
 * and integer index based constructors to provide for JDBC RowSet Implementation
 * applications that use both column identification conventions.
