this method skips the first skipNum documents in the iterator. When skipNum is large enough to skip past the last
HippoDocumentBean, then no error will be thrown, but this method returns. The Iterator.hasNext() will then return false
Parameters:
skipNum -
getPosition
intgetPosition()
Returns the current position within the iterator. The number
returned is the 0-based index of the next element in the iterator,
i.e. the one that will be returned on the subsequent next call.
Note that this method does not check if there is a next element,
i.e. an empty iterator will always return 0.
