Example 2 with Relation

use of uk.me.parabola.mkgmap.reader.osm.Relation in project mkgmap by openstreetmap.

the class ActionReaderTest method testApplyAction.

/**
 * The apply action works on the members of relations.
 */

    rule.resolveType(rel, TypeResult.NULL_RESULT);
    assertNull("Tag not set on relation", rel.getTag("route"));

Example 3 with Relation

use of uk.me.parabola.mkgmap.reader.osm.Relation in project mkgmap by openstreetmap.

the class ActionReaderTest method testApplyWithRole.

/**
 * You can have a role filter, so that the actions are only applied
 * to members with the given role.

Example 4 with Relation

use of uk.me.parabola.mkgmap.reader.osm.Relation in project mkgmap by openstreetmap.
