public class ExcelXStreamExporter
extends ExcelXExporter

Different implementation of ExcelXExporter using the POI streaming API: SXSSF (package: org.apache.poi.xssf.streaming) is an API-compatible streaming extension of XSSF to be used when very large spreadsheets have to be produced, and heap space is limited. SXSSF achieves its low memory footprint by limiting access to the rows that are within a sliding window.
