public class SharedExcelRowReaderFactory
extends ExcelRowTokenizerFactory

Description: ExcelRowTokenizerFactory that supports multiple imports on the same excel workbook. This is useful if multiple sheets should be imported by keeping the workbook instance open until it is explictly closed.

This class is not thread-safe!

Example 1:

     InputStream stream = new FileInputStream("workbook.xls");
     ExcelRowTokenizerFactory factory = new SharedExcelRowReaderFactory(stream, true);
     try {
        ImporterSpec spec1 = new ExcelImporterSpec("SheetName1") {
         protected void processRow(ExcelImportProcessor processor) throws ImporterException {
              processor.getString("column title 1"));
              processor.getBoolean("column title 2"));
           }
        };
        spec1.setLineTokenizerFactory(factory);
        Importer importer1 = new Importer(spec1);
        importer1.importFrom((InputStream) null);


        ImporterSpec spec2 = new ExcelImporterSpec("SheetName2") { ... };
        spec2.setLineTokenizerFactory(factory);
        Importer importer2 = new Importer(spec2);
        importer2.importFrom((InputStream) null);

     } finally {
      stream.close();
     }
 

or Example 2:

     InputStream stream = new FileInputStream("workbook.xls");
     ExcelRowTokenizerFactory factory = new SharedExcelRowReaderFactory();
     try {
        ImporterSpec spec1 = new ExcelImporterSpec("SheetName1") { ... };
        spec1.setLineTokenizerFactory(factory);
        Importer importer1 = new Importer(spec1);
        importer1.importFrom(stream);


        ImporterSpec spec2 = new ExcelImporterSpec("SheetName2") { ... };
        spec2.setLineTokenizerFactory(factory);
        Importer importer2 = new Importer(spec2);
        importer2.importFrom(stream);

     } finally {
      stream.close();
     }
