Class BufferResultMatcher

java.lang.Object

org.locationtech.jtstest.testrunner.BufferResultMatcher

All Implemented Interfaces:

ResultMatcher

public class BufferResultMatcher
extends Object
implements ResultMatcher

A ResultMatcher which compares the results of buffer operations for equality, up to the given tolerance. All other operations are delagated to the standard EqualityResultMatcher algorithm.

• Constant Field Values

MAX_HAUSDORFF_DISTANCE_FACTOR

private static final double MAX_HAUSDORFF_DISTANCE_FACTOR

See Also:

• Constant Field Values

MIN_DISTANCE_TOLERANCE

private static final double MIN_DISTANCE_TOLERANCE

The minimum distance tolerance which will be used. This is required because densified vertices do no lie precisely on their parent segment.

BufferResultMatcher

public BufferResultMatcher()

Method Details

isMatch

public boolean isMatch(Geometry geom,
 String opName,
 Object[] args,
 Result actualResult,
 Result expectedResult,
 double tolerance)

Tests whether the two results are equal within the given tolerance. The input parameters are not considered.

Specified by:

isMatch in interface ResultMatcher

Parameters:

geom - the target geometry

opName - the operation performed

args - the input arguments to the operation

actualResult - the actual computed result

expectedResult - the expected result of the test

tolerance - the tolerance for the test

Returns:

true if the actual and expected results are considered equal
