Document

Returns the extract type, which determines whether data is read from one row or one column of the underlying dataset.

Usage

From source file:org.jfree.data.category.CategoryToPieDatasetTest.java

/**
 * Serialize an instance, restore it, and check for equality.
 *//*from   w  w w .  ja v a 2  s .  co m*/
@Test
public void testSerialization() {
    DefaultCategoryDataset underlying = new DefaultCategoryDataset();
    underlying.addValue(1.1, "R1", "C1");
    underlying.addValue(2.2, "R1", "C2");
    CategoryToPieDataset d1 = new CategoryToPieDataset(underlying, TableOrder.BY_COLUMN, 1);
    CategoryToPieDataset d2 = (CategoryToPieDataset) TestUtilities.serialised(d1);
    assertEquals(d1, d2);

    // regular equality for the datasets doesn't check the fields, just
    // the data values...so let's check some more things...
    assertEquals(d1.getUnderlyingDataset(), d2.getUnderlyingDataset());
    assertEquals(d1.getExtractType(), d2.getExtractType());
    assertEquals(d1.getExtractIndex(), d2.getExtractIndex());
}
