Class GeometryCollector
Object
GeometryCollector
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)

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
Returns the geometry factory used to deep clone the geometries while collecting them (if null no cloning will happen) -
setFactory
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 onPackedCoordinateSequenceFactory
is used to minimize the memory usage -
collect
Returns a geometry collection containing all of the geometries collected in the process -
