      Description

      Add RowLimitMutator interface for cases where row limit can be mutated.

      package org.apache.myfaces.trinidad.model;

      /**

      • Identifies a collection whose row limit can be mutated.
        */
        public interface RowLimitMutator { /** * Mutate the row limit of this collection, it returns the old row limit. * @param newLimit the new limit of this collection to set to. * A positive number: the maximum number of rows the collection can hold. * CollectionModel.UNKNOWN_ROW_LIMIT: row limit is unknown. * CollectionModel.UNLIMITED_ROW: there is no limit * @returns the old row limit. * @throws IllegalArgumentException if <em>newLimit</em> is 0 or any negative number * other than CollectionModel.UNKNOWN_ROW_LIMIT and CollectionModel.UNLIMITED_ROW. */ public int setRowLimit(int newLimit); }

      CollectionModel is updated to define the row limit constants, and also provides the default implementation of retrieving row limit method.

      /**

      • Gets the row limit of this collection model. Default is to return UNKNOWN_ROW_LIMIT.
      • Subclasses should override this method if row limit is enforced.
      • @return the maximum number of rows this collection can hold, possible return values are:
      • A positive number: the maximum number of rows the collection can hold
      • UNKNOWN_ROW_LIMIT: row limit is unknown.
      • UNLIMITED_ROW: there is no limit
        */
        public int getRowLimit() { return UNKNOWN_ROW_LIMIT; }

      public final static int UNLIMITED_ROW = -2;
      public final static int UNKNOWN_ROW_LIMIT = -1;
