GeoJSONGeometryWriter

public GeoJSONGeometryWriter()

Constructs a new GeoJSONGeometryWriter object with default settings.

方法详细资料

getCPtr

public static long getCPtr(GeoJSONGeometryWriter obj)

finalize

protected void finalize()

覆盖:

finalize 在类中 java.lang.Object

delete

public void delete()

getSourceProjection

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.

返回:

The current source projection or null.

setSourceProjection

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.

参数:

proj - The new source projection or null.

getZ

public boolean getZ()

Returns the state of Z coordinate serialization.

返回:

True if Z coordinate is stored in GeoJSON output, false otherwise. The default is false.

setZ

public void setZ(boolean z)

Sets the state of Z coordinate serialization.

参数:

z - True when Z coordinate should be serialized, false otherwise.

writeGeometry

public java.lang.String writeGeometry(Geometry geometry)

Creates a GeoJSON string corresponding to the specified geometry.

参数:

geometry - The geometry to write.

返回:

The corresponding GeoJSON string.

抛出:

java.lang.Exception - If string could not be generated.

writeFeature

public java.lang.String writeFeature(Feature feature)

Creates a GeoJSON string corresponding to the specified feature.

参数:

feature - The feature to write.

返回:

The corresponding GeoJSON string.

抛出:

java.lang.Exception - If string could not be generated.

writeFeatureCollection

public java.lang.String writeFeatureCollection(FeatureCollection featureCollection)

Creates a GeoJSON string corresponding to the specified feature collection.

参数:

featureCollection - The feature collection to write.

返回:

The corresponding GeoJSON string.

抛出:

java.lang.Exception - If string could not be generated.
