Examples of com.google.dart.engine.index.Location

com.google.dart.engine.index.Location
Instances of the class Location represent a location related to an element. The location is expressed as an offset and length, but the offset is relative to the resource containing the element rather than the start of the element within that resource. @coverage dart.engine.index

        int offset = property.getFieldNameOffset();
        if (offset == -1) {
          continue;
        }
        int length = field.getName().length();
        Location location = new Location(property, offset, length);
        // getter reference
        if (property.getPropertyKind().callsGetter()) {
          PropertyAccessorElement getter = field.getGetter();
          if (getter != null) {
            store.recordRelationship(getter, IndexConstants.IS_REFERENCED_BY_QUALIFIED, location);
