Public Constructors
public GeoJSONGeometryWriter ()
Constructs a new GeoJSONGeometryWriter object with default settings.
Public Methods
public synchronized void delete ()
public Projection getSourceProjection ()
Returns the current source projection. If source projection is set, all geometry
coordinates will be converted from given coordinate system to WGS84.
Returns
- The current source projection or null.
public boolean getZ ()
Returns the state of Z coordinate serialization.
Returns
- True if Z coordinate is stored in GeoJSON output, false otherwise. The default is false.
public void setSourceProjection (Projection proj)
Sets the current source projection. If source projection is set, all geometry
coordinates will be converted from given coordinate system to WGS84.
Parameters
| proj | The new source projection or null. |
|---|
public void setZ (boolean z)
Sets the state of Z coordinate serialization.
Parameters
| z | True when Z coordinate should be serialized, false otherwise. |
|---|
public String writeFeature (Feature feature)
Creates a GeoJSON string corresponding to the specified feature.
Parameters
| feature | The feature to write. |
|---|
Returns
- The corresponding GeoJSON string.
Throws
| Exception | If string could not be generated. |
|---|
public String writeFeatureCollection (FeatureCollection featureCollection)
Creates a GeoJSON string corresponding to the specified feature collection.
Parameters
| featureCollection | The feature collection to write. |
|---|
Returns
- The corresponding GeoJSON string.
Throws
| Exception | If string could not be generated. |
|---|
public String writeGeometry (Geometry geometry)
Creates a GeoJSON string corresponding to the specified geometry.
Parameters
| geometry | The geometry to write. |
|---|
Returns
- The corresponding GeoJSON string.
Throws
| Exception | If string could not be generated. |
