Method Detail

wkb2Geometry

public Geometry wkb2Geometry(byte[] wkbBytes)
                      throws IOException

This method will convert a Well Known Binary representation to a JTS Geometry object.

Returns:

a JTS Geometry object that is equivalent to the WTB representation passed in by param wkb

Throws:

IOException - if more than one geometry object was found in the WTB representation, or if the parser could not parse the WKB representation.
