public class RMTableOfContents
extends java.util.HashMap

This Hashtable subclass provides page number information for table rows in a generated report for the purpose of generating a table of contents. It is initialized from a previously generated report and provides Lists of table row data for keys of the form "Table-DatasetKey.Table-Grouping-Key" from the original report. Tables based on these Dataset keys can then reference any key from the original set of objects (and any key available to the Details table row for that grouping) and also the keys "page" and "row". Here's an example of using RMTableOfContents:

    // Generate report normally
    RMDocument template = RMDocument.getDoc("MyTemplate.rpt");
    RMDocument report = template.generateReport(myObjects);
    
    // Get table of contents and generate that report
    RMTableOfContents toc = new RMTableOfContents(report);
    RMDocument tocTemplate = RMDocument.getDoc("MyTemplateTOC.rpt");
    RMDocument report2 = tocTemplate.generateReport(toc);
    
    // Append original report to table of contents and get PDF
    report2.addPages(report);
    report2.writePDF("MyReport.pdf");

In this example, the tocTemplate would be a simple template with a Table who's DatasetKey is equal to some Table-DatasetKey.Table-Grouping-Key from the original report (eg., "getMovies.getStudio", for our typical Hollywood example, where the original template has a "getMovies" table, with a grouping on the key "getSudio"). In addition to a large header row (that maybe says, "Hollywood Report - - Table of Contents"), this table would have a details row configured with a column of the form "@row@. @getStudio.getName@ ........ @page@". Additionally, the template might want to set the URL for the Details table row to "Page:@page@" so that the table of contents entries are actually hyperlinks to the appropriate page. It may be interesting to note (as an implementation detail only) that the "page" key in an RMTableOfContents entry actually returns the page number relative to the end of the document, in the form of a key itself, for example: "@PageMax-N@" (which gets re-evaluated before PDF generation), so that it can compensate for the length of the Table of Contents table itself. Also, RMTableOfContents uses lower case versions of the common keys @row@ and
