GROUNDED
Property value: the iterator is "grounded". This means that (a) the iterator must be an instance ofGroundedIterator
, 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
Property value: the iterator knows the number of items that it will deliver. This means that (a) the iterator must be an instance ofLastPositionFinder
, 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
Property value: the iterator knows whether there are more items still to come. This means that (a) the iterator must be an instance ofLookaheadIterator
, and (b) the implementation of the hasNext() method must be efficient (more efficient than the client doing it) -
ATOMIZING
Property value: the iterator can deliver an atomized result. This means that the iterator must be an instance ofAtomizingIterator
.

values
Returns an array containing the constants of this enum type, in the order they are declared.- Returns:
- an array containing the constants of this enum type, in the order they are declared

name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException
