Constructor Detail

OfferIterator

public OfferIterator(Offer[] values)

Method Detail

max_left

public int max_left()
             throws UnknownMaxLeft

Description copied from interface: OfferIteratorOperations

The max_left operation returns the number of service offers remaining in the iterator. The exception UnknownMaxLeft is raised if the iterator cannot determine the remaining number of service offers (e.g., if the iterator determines its set of service offers through lazy evaluation).

Throws:

UnknownMaxLeft

next_n

public boolean next_n(int n,
                      OfferSeqHolder offers)

Description copied from interface: OfferIteratorOperations

The next_n operation returns a set of service offers in the output parameter offers. The operation returns n service offers if there are at least n service offers remaining in the iterator. If there are fewer than n service offers in the iterator, then all remaining service offers are returned. The actual number of service offers returned can be determined from the length of the offers sequence. The next_n operation returns TRUE if there are further service offers to be extracted from the iterator. It returns FALSE if there are no further service offers to be extracted.

destroy

public void destroy()

Destroys the iterator
