Modifier	Constructor and Description
private	MySqlGeometry(byte[] wkb) Create a MySqlGeometry using the supplied wkb, note this should be the cleaned wkb for MySQL

Method Summary

Modifier and Type	Method and Description
private static byte[]	convertToWkb(byte[] source) Since MySQL prepends 4 bytes as type prefix, we remove those bytes in order to have a valid WKB representation
static MySqlGeometry	fromBytes(byte[] mysqlBytes) Create a MySqlGeometry from the original byte array from MySQL binlog event
mil.nga.wkb.geom.Point	getPoint() It returns a Point coordinate according to OpenGIS based on the WKB
byte[]	getWkb() Returns the standard well-known binary representation of the MySQL byte
