Method Detail

lookupRule

public SpatialRule lookupRule(double lat,
                              double lon)

Description copied from interface: SpatialRuleLookup

Return an applicable rule for this location. If there is more than one rule for the location, the implementation can decide which rule to return. For example this might be the first occurring or the most relevant, see the implementation JavaDoc.

If the requested location is outside of the supported bounds or no SpatialRule is registered at this location SpatialRule.EMPTY is returned.

lookupRule

public SpatialRule lookupRule(GHPoint point)

Description copied from interface: SpatialRuleLookup

See SpatialRuleLookup.lookupRule(double, double) for details.

Specified by:

lookupRule in interface SpatialRuleLookup

getSpatialId

public int getSpatialId(SpatialRule rule)

Description copied from interface: SpatialRuleLookup

This method returns an identification number from 0 to size (exclusive) for the specified rule. The id is fix for a given set of SpatialRules.

Specified by:

getSpatialId in interface SpatialRuleLookup

getSpatialRule

public SpatialRule getSpatialRule(int spatialId)

Description copied from interface: SpatialRuleLookup

This method returns the SpatialRule for a given Spatial Id. This can be used when retrieving SpatialRules from a Spatial Id stored in the graph.

Specified by:

getSpatialRule in interface SpatialRuleLookup

size

public int size()

Specified by:

size in interface SpatialRuleLookup

Returns:

the number of rules added to this lookup.

getBounds

public org.locationtech.jts.geom.Envelope getBounds()

Specified by:

getBounds in interface SpatialRuleLookup

Returns:

the bounds of the SpatialRuleLookup
