Interface AsyncObjectSizeQueue<T extends ObjectId>

Type Parameters:

T - type of identifier supplied to the call that made the queue.

All Superinterfaces:

AsyncOperation

public interface AsyncObjectSizeQueue<T extends ObjectId>
extends AsyncOperation

Queue to examine object sizes asynchronously. A queue may perform background lookup of object sizes and supply them (possibly out-of-order) to the application.

Method Summary

T	getCurrent()
ObjectId	getObjectId()
long	getSize()
boolean	next() Position this queue onto the next available result.

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 objects getCurrent() 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()

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()

Returns:

the ObjectId of the current object. Never null.

getSize

long getSize()

Returns:

the size of the current object.
