writeGeometry method

void writeGeometry(Geometry geom, ValueSetter dest)

Parse a geometry starting at offset. @param geom the geometry to write @param dest the value setting to be used for writing

Implementation

void writeGeometry(Geometry geom, ValueSetter dest) {
  // write endian flag
  dest.setByte(dest.endian);

  EGeometryType geometryType = EGeometryType.forGeometry(geom);

  // write typeword
  int typeword = geometryType.getTypeCode(geom);

    //geom.dimension == 3) {
    typeword |= 0x80000000;
  }
  if (typeword > 1999) {
    //geom.haveMeasure) {
    typeword |= 0x40000000;
  }
  if (geom.getSRID() != BinaryParser.UNKNOWN_SRID) {
    typeword |= 0x20000000;
  }

  dest.setInt(typeword);

  if (geom.getSRID() != BinaryParser.UNKNOWN_SRID) {
    dest.setInt(geom.getSRID());
  }
