org.openstreetmap.atlas.checks.validation.intersections.SelfIntersectingPolylineCheck

All Implemented Interfaces:

java.io.Serializable, Check

public class SelfIntersectingPolylineCheck
extends BaseCheck<java.lang.Long>

BaseCheck that identifies self-intersecting PolyLines within Areas, Edges and Lines. Both shape point and non-shape point intersections are flagged.

Constructor Detail

SelfIntersectingPolylineCheck

public SelfIntersectingPolylineCheck(org.openstreetmap.atlas.utilities.configuration.Configuration configuration)

Default constructor

Parameters:

configuration - the JSON configuration for this check

Method Detail

validCheckForObject

public boolean validCheckForObject(org.openstreetmap.atlas.geography.atlas.items.AtlasObject object)

Checks to see whether the atlas object has the prerequisites to be evaluated. It uses a function BaseCheck.isFlagged(Object) that looks through a list of elements that have been flagged by the check algorithm, and if the check has already looked at a specific feature it can skip it here. This is useful if you are walking the graph in your check algorithm and then can flag each feature that you visit while walking the graph.

Parameters:

object - the AtlasObject you are checking

Returns:

true if object should be checked

flag

protected java.util.Optional<CheckFlag> flag(org.openstreetmap.atlas.geography.atlas.items.AtlasObject object)

Specified by:

flag in class BaseCheck<java.lang.Long>

getFallbackInstructions

protected java.util.List<java.lang.String> getFallbackInstructions()

Description copied from class: BaseCheck

Method to implement for inheriting checks to return the default set of instruction formats that will be the last resort in BaseCheck.getLocalizedInstruction(int, Object[])

Overrides:

getFallbackInstructions in class BaseCheck<java.lang.Long>

Returns:

The set of instructions to fall back to if configuration results in none.
