Package nz.org.riskscape.engine.projection

Class ValidateGeometryProjection

java.lang.Object
nz.org.riskscape.engine.projection.ValidateGeometryProjection
All Implemented Interfaces:
nz.org.riskscape.engine.projection.Projection
public class ValidateGeometryProjection extends Object implements nz.org.riskscape.engine.projection.Projection

A projection that detects any invalid Geometry and throws InvalidTupleException should an invalid geometry be found.

Note that this projector only checks geometries that are in the top level of the sourceType (nested geometry members are not checked). If there are no geometries in the top level of sourceType of if mode is GeometryValidation.OFF then the affect is an identity projection.

Invalid Geometry can cause TopologyExceptions later if we try to manipulate the Geometry at all (i.e. take an intersection). It's simpler to alert the user at this point rather than trying to catch a TopologyException later.
