Class OrthoLineFeatureBuilder

  • public class OrthoLineFeatureBuilder
extends GridFeatureBuilder
    A basic implementation of LineFeatureBuilder which will create a SimpleFeatureType having two properties:
    • element - TYPE LineString
    • id - TYPE Integer
    The attribute names can also be referred to using LineFeatureBuilder#DEFAULT_GEOMETRY_ATTRIBUTE_NAME and ID_ATTRIBUTE_NAME

    Line elements will be assigned sequential id values starting with 1.
