Method Detail

getTotalEstimatedWorkSize

int getTotalEstimatedWorkSize()

Get an estimate of the total number of objects that will be provided by this instance. Instances can provide accurate answers on each call, but only if the answer can be provided quickly and efficiently; usually it is enough to to cache the result after providing an initial estimate.

Returns:

a total work size estimate

getNextWork

java.util.Collection getNextWork()

Get the next lot of work for the batch processor. Implementations should return the largest number of entries possible; the BatchProcessor will keep calling this method until it has enough work for the individual worker threads to process or until the work load is empty.

Returns:

the next set of work object to process or an empty collection if there is no more work remaining.
