Package org.geotools.data

Class DataTestCase

Object

DataTestCase

public abstract class DataTestCase
extends Object

A set of constructs and utility methods used to test the data module.

By isolating a common set of SimpleFeatures, SimpleFeatureTypes and Filters we are able to reduce the amount of overhead in setting up new tests.

This code has been made part of the public geotools.jar to provide a starting point for test cases involving Data constructs.

Method Details

expected

protected int expected(Filter filter)

init

public void init()
          throws Exception

Invoked before a test is run. The default implementation invokes dataSetUp().

Throws:

Exception

dataSetUp

protected void dataSetUp()
                  throws Exception

Loads the data.

Throws:

Exception

See Also:

• init()

tearDown

public void tearDown()
              throws Exception

Set all data references to null, allowing garbage collection. This method is automatically invoked after each test.

Throws:

Exception

line

public LineString line(int[] xy)

Creates a line from the specified (x,y) coordinates. The coordinates are stored in a flat array.

lines

public MultiLineString lines(int[][] xy)

Creates a multiline from the specified (x,y) coordinates.

polygon

public Polygon polygon(int[] xy)

Creates a polygon from the specified (x,y) coordinates. The coordinates are stored in a flat array.

polygon

public Polygon polygon(int[] xy,
 int[][] holes)

Creates a line from the specified (x,y) coordinates and an arbitrary amount of holes.

ring

public LinearRing ring(int[] xy)

Creates a ring from the specified (x,y) coordinates. The coordinates are stored in a flat array.

assertGeometryEquals

protected void assertGeometryEquals(Geometry expected,
 Geometry actual)

Compares two geometries for equality.

assertGeometryEquals

protected void assertGeometryEquals(String message,
 Geometry expected,
 Geometry actual)

Compares two geometries for equality.

count

protected int count(FeatureReader<SimpleFeatureType,SimpleFeature> reader)
             throws IOException

Counts the number of Features returned by the specified reader.

This method will close the reader.

Throws:

IOException

count

protected int count(FeatureWriter<SimpleFeatureType,SimpleFeature> writer)
             throws NoSuchElementException,
IOException

Counts the number of Features in the specified writer. This method will close the writer.

Throws:

NoSuchElementException

IOException
