Constructor Detail

DB2WKBWriter

public DB2WKBWriter(boolean hasOGCWkbZTyps)

Creates a writer that writes Geometry using BIG_ENDIAN byte order. If the input geometry has a small coordinate dimension, coordinates will be padded with NULL_ORDINATE.

DB2WKBWriter

public DB2WKBWriter(int byteOrder,
                    boolean hasOGCWkbZTyps)

Creates a writer that writes Geometrys in the given byte order If the input geometry has a small coordinate dimension, coordinates will be padded with NULL_ORDINATE.

Parameters:

byteOrder - the byte ordering to use

Method Detail

guessCoordinateDimension

public static final int guessCoordinateDimension(Geometry g)

returns the coordinate dimension for a geometry

Parameters:

g - the geometry

Returns:

if there is one z value != NaN, then 3 else 2

bytesToHex

public static String bytesToHex(byte[] bytes)

write

public byte[] write(Geometry geom)

Writes a Geometry into a byte array.

Parameters:

geom - the geometry to write

Returns:

the byte array containing the WKB

write

public void write(Geometry geom,
                  OutStream os)
           throws IOException

Writes a Geometry to an OutStream.

Parameters:

geom - the geometry to write

os - the out stream to write to

Throws:

IOException - if an I/O error occurs

getOutputDimension

public int getOutputDimension()
