org.pentaho.reporting.engine.classic.core.function.TotalItemCountFunction

A report function that counts the total number of items contained in groups in a report. If no groupname is given, all items of the report are counted.

Like all Total-Functions, this function produces a precomputed grand total. The function's result is precomputed once and will not change later. Printing the result of this function in a group header returns the same value as printed in the group-footer.

The ItemCount can be used to produce a running row-count for a group or report.

To count the number of groups in a report, use the TotalGroupCountFunction. @author Thomas Morgner

    if (g != null)
    {
      report.removeGroup(g);
    }


    TotalItemCountFunction f = new TotalItemCountFunction();
    f.setName("continent-total-gc");
    f.setGroup("Continent Group");
    f.setDependencyLevel(1);
    report.addExpression(f);


    TotalItemCountFunction f2 = new TotalItemCountFunction();
    f2.setName("total-gc");
    f2.setDependencyLevel(1);
    report.addExpression(f2);


    assertTrue(FunctionalityTestLib.execGraphics2D(report));
