Class GeometryCollector

Object
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 Details

    • 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

    • collectInternal

      public GeometryCollection collectInternal()

    • add

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