org.apache.flink.test.recordJobs.util.Tuple.project()
Performs a projection on the tuple. The int parameter is interpreted as a bitmap on the columns. I.e. a bitmap value of 1 projects to the first column, 2 to the second, 3 to the first two columns, and so on. @param bitmap the projection bitmap.

    Assert.assertTrue(t.getNumberOfColumns() == 3);
    Assert.assertTrue(t.getStringValueAt(0).equals("a"));
    Assert.assertTrue(t.getStringValueAt(1).equals("b"));
    Assert.assertTrue(t.getStringValueAt(2).equals("d"));
    
    t.project(-1);
    Assert.assertTrue(t.getNumberOfColumns() == 3);
    Assert.assertTrue(t.getStringValueAt(0).equals("a"));
    Assert.assertTrue(t.getStringValueAt(1).equals("b"));
    Assert.assertTrue(t.getStringValueAt(2).equals("d"));
