Class GeometryCollector

  • public class GeometryCollector
    extends Object
    A stateful geometry collector that will add all geometries into a single resulting geometry collection with the following properties:
    • the elements of the resulting geometry are simple geometries, adding a geometry collection will result in it being flattened
    • the resulting geometry collection type will match its contents, a generic geometry collection will be used only in case of heterogeneous contents
    • all geometries will be cloned using the provided geometry factory (one based on a PackedCoordinateSequence is used by default to reduce memory usage)

        public GeometryCollector()
    • Method Detail

      • getMaxCoordinates

        public long getMaxCoordinates()
        Returns the maximum number of coordinates this collector is allowed to keep in the resulting geometry
      • setMaxCoordinates

        public void setMaxCoordinates​(long maxCoordinates)
        Sets the maximum number of coordinates to be collected. By default is -1, no limit
      • getFactory

        public GeometryFactory getFactory()
        Returns the geometry factory used to deep clone the geometries while collecting them (if null no cloning will happen)
      • setFactory

        public void setFactory​(GeometryFactory factory)
        Sets the geometry factory used to deep clone the geometries while collecting them. May be set to null to avoid deep cloning. By default a geometry factory based on PackedCoordinateSequenceFactory is used to minimize the memory usage
      • collect

        public GeometryCollection collect()
        Returns a geometry collection containing all of the geometries collected in the process
      • add

        public void add​(Geometry g)
        Adds a geometry to the collector
