Method Detail

next
boolean next() throws MissingObjectException, IOException
Position this queue onto the next available result.- Returns:
- true if there is a result available; false if the queue has finished its input iteration.
- Throws:
MissingObjectException
- the object does not exist. If the implementation is retaining the application's objectsgetCurrent()
will be the current object that is missing. There may be more results still available, so the caller should continue invoking next to examine another result.IOException
- the object store cannot be accessed.
-
getCurrent
T getCurrent()
getCurrent.
- Returns:
- the current object, null if the implementation lost track.
Implementations may for performance reasons discard the caller's
ObjectId and provider their own through
getObjectId()
.
-
getObjectId
ObjectId getObjectId()
Get the ObjectId of the current object. Never null.- Returns:
- the ObjectId of the current object. Never null.
-
