      Enum Constants 
      Enum Constant Description
      ATOMIZING
      Property value: the iterator can deliver an atomized result.
      GROUNDED
      Property value: the iterator is "grounded".
      LAST_POSITION_FINDER
      Property value: the iterator knows the number of items that it will deliver.
      LOOKAHEAD
      Property value: the iterator knows whether there are more items still to come.

      • GROUNDED

        public static final SequenceIterator.Property GROUNDED
        Property value: the iterator is "grounded". This means that (a) the iterator must be an instance of GroundedIterator, and (b) the implementation of the materialize() method must be efficient (in particular, it should not involve the creation of new objects)
      • LAST_POSITION_FINDER

        public static final SequenceIterator.Property LAST_POSITION_FINDER
        Property value: the iterator knows the number of items that it will deliver. This means that (a) the iterator must be an instance of LastPositionFinder, and (b) the implementation of the getLastPosition() method must be efficient (in particular, it should take constant time, rather than time proportional to the length of the sequence)
      • LOOKAHEAD

        public static final SequenceIterator.Property LOOKAHEAD
        Property value: the iterator knows whether there are more items still to come. This means that (a) the iterator must be an instance of LookaheadIterator, and (b) the implementation of the hasNext() method must be efficient (more efficient than the client doing it)

      • values

        public static SequenceIterator.Property[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (SequenceIterator.Property c : SequenceIterator.Property.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static SequenceIterator.Property valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
