Method Details

swap

public static GeometryBytes swap(GeometryBytes geometry)

Swap geometry coordinates using default spatial reference identifiers.

Parameters:

geometry - geometry, should not be null

Returns:

a new geometry instance with coordinates swapped if SRID matched

swap

public static GeometryBytes swap(GeometryBytes geometry,
 int... srids)

Swap geometry coordinates using default spatial reference identifiers.

Parameters:

geometry - geometry, should not be null

srids - list of SRIDs to filter whether to swap coordinates by

Returns:

a new geometry instance with coordinates swapped if SRID matched

swapNoCheck

public static GeometryBytes swapNoCheck(GeometryBytes geometry)

Swap geometry coordinates, as long as an SRID is present.

Parameters:

geometry - geometry, should not be null

Returns:

a new geometry instance with coordinates swapped or existing geometry if no SRID is set

needsSwapping

private static boolean needsSwapping(int srid,
 int[] allowedSrids)

swapCoordinates

private static byte[] swapCoordinates(byte[] wkb)
