io.github.sebasbaumh.postgis.binary.BinaryWriter

public final class BinaryWriter
extends Object

Create binary representation of geometries. Currently, only text rep (hexed) implementation is tested. It should be easy to add char[] and CharSequence ByteGetter instances, although the latter one is not compatible with older jdks. I did not implement real unsigned 32-bit integers or emulate them with long, as both java Arrays and Strings currently can have only 2^31-1 elements (bytes), so we cannot even get or build Geometries with more than approx. 2^28 coordinates (8 bytes each).

Method Details

writeBinary

public static byte[] writeBinary(Geometry geom)

Write a binary encoded geometry. The geometry you put in must be consistent, geom.checkConsistency() must return true. If not, the result may be invalid WKB.

Parameters:

geom - the geometry to be written

Returns:

byte arrray containing the encoded geometry

writeHexed

public static String writeHexed(Geometry geom)

Write a hex encoded geometry. The geometry you put in must be consistent, geom.checkConsistency() must return true. If not, the result may be invalid WKB.

Parameters:

geom - the geometry to be written

Returns:

String containing the hex encoded geometry
