Interface IVertexValuator

All Known Implementing Classes:

VertexValuatorDefault

public interface IVertexValuator

An interface for specifying methods of accessing a value from a Vertex.

Clearly, the most straight-forward way to create a surface from a sample of vertices is by accessing their Z coordinates. But in cases where a derived value is required, or where a value needs to be computed using information available to the application but outside the scope of the TIN implementation, this interface provides a mechanism for doing so.

Development Notes

For a default implementation, see the VertexValuatorGetZ class.

The functionality provided by this interface seems like a natural candidate for the Java closure concept introduced with Java 8. At the time of this implementation, Java 8 is only a few months old and not yet in wide use. This design decision may be revisited later.
