      Specified by:
      treatAs in interface BlazeJoin<Z,K>
      Type Parameters:
      T - The target treat type
      Parameters:
      type - type to be downcast to
      Returns:
      The treated join object

    • on

      BlazeMapJoin<Z,K,V> on(Expression<Boolean> restriction)

      on in interface BlazeJoin<Z,K>
      Parameters:
      restriction - a simple or compound boolean expression

      the modified join object

    • on

      BlazeMapJoin<Z,K,V> on(Predicate... restrictions)
