QueryIterSlice

public QueryIterSlice(QueryIterator cIter,
 long startPosition,
 long numItems,
 ExecutionContext context)

Create an iterator that limits the number of returns of another CloseableIterator.

Parameters:

cIter - The closable iterator to throttle

startPosition - Offset of start after - 0 is the no-op.

numItems - Maximum number of items to yield.
