Method Detail

fromWkt

public static <P extends Position> Geometry<P> fromWkt(java.lang.String wkt,
                                                       CoordinateReferenceSystem<P> crs)

Decodes the specified WKT String to a Geometry.

This method uses the default WKT dialect (Postgis v1.5 EWKT)

Parameters:

wkt - the WKT string to decode

Returns:

The decoded Geometry

fromWkt

public static Geometry<?> fromWkt(java.lang.String wkt)

toWkt

public static java.lang.String toWkt(Geometry<?> geometry)

Encodes a Geometry to a WKT representation.

This method uses the default WKT dialect (Postgis v1.5 EWKT)

Parameters:

geometry - the Geometry to encode

Returns:

the WKT representation of the given geometry

newDecoder

public static WktDecoder newDecoder(Wkt.Dialect dialect)

Creates a WktDecoder for the specified WKT Dialect.

Parameters:

dialect - the WKT dialect

Returns:

an WktDecoder that supports the specified dialect

newDecoder

public static WktDecoder newDecoder()

Creates a WktDecoder for the default dialect (Postgis 1.x EWKT).

Returns:

an WktDecoder that supports the default dialect

newEncoder

public static WktEncoder newEncoder(Wkt.Dialect dialect)

Creates a WktEncoder for the specified WKT Dialect.

Parameters:

dialect - the WKT dialect

Returns:

an WktEncoder that supports the specified dialect

newEncoder

public static WktEncoder newEncoder()

Creates a WktEncoder for the default dialect (Postgis 1.x EWKT).

Returns:

an WktEncoder that supports the default dialect

createInstance

private static <T> T createInstance(java.lang.Class<? extends T> codecClass)
