Method Detail

iterator

public CloseableIterator<org.apache.poi.ss.usermodel.Row> iterator()

Returns a new streaming iterator to loop through rows. This iterator is not guaranteed to have all rows in memory, and any particular iteration may trigger a load from disk to read in new data. This is an iterator of the PHYSICAL rows. Meaning the 3rd element may not be the third row if say for instance the second row is undefined. This behaviour changed in v4.0.0. Earlier versions only created one iterator and repeated calls to this method just returned the same iterator. Creating multiple iterators will slow down your application and should be avoided unless necessary.

Specified by:

iterator in interface java.lang.Iterable<org.apache.poi.ss.usermodel.Row>

Returns:

the streaming iterator, an instance of CloseableIterator - it is recommended that you close the iterator when finished with it if you intend to keep the sheet open.
