Class BinaryWriter

  • public class BinaryWriter
extends java.lang.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).

        Parameters:
        geom - the geometry to write

      • writeHexed

        public static java.lang.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
