Example 92 with NPOIFSFileSystem

use of org.apache.poi.poifs.filesystem.NPOIFSFileSystem in project poi by apache.

the class HSSFWorkbook method write.

/**
     * Method write - write out this workbook to an {@link OutputStream}. Constructs
     * a new POI POIFSFileSystem, passes in the workbook binary representation and
     * writes it out.
     * 
     * If {@code stream} is a {@link java.io.FileOutputStream} on a networked drive
     * or has a high cost/latency associated with each written byte,
     * consider wrapping the OutputStream in a {@link java.io.BufferedOutputStream}
     * to improve write performance.
     *
     * @param stream - the java OutputStream you wish to write the XLS to
     *
     * @exception IOException if anything can't be written.
     * @see org.apache.poi.poifs.filesystem.POIFSFileSystem
