Interface Offsets

public interface Offsets

The interface Offsets defines the basic structure to deal with offsets. The OpenLR method defines two offsets: positive offset and negative offset. The positive offset indicates the distance between start point of the first line and the real start point of the location. The negative offset indicates the distance between end point of the last line and the real end point of the location. Offsets are not mandatory in OpenLR and using no offsets means that the location starts at the start node of the first line and ends at the end node of the last line of the location. It is also possible to use only one offset value.
