/**
 * Type safe enum for an SSL/TLS protocol version. Instances are obtained
 * using the static factory methods or by referencing the static members
 * in this class. Member variables are final and can be accessed without
 * accessor methods.
 *
 * There is only ever one instance per supported protocol version, this
 * means == can be used for comparision instead of equals() if desired.
 *
 * Checks for a particular version number should generally take this form:
 *
 * if (protocolVersion.v >= ProtocolVersion.TLS10) {
 *   // TLS 1.0 code goes here
 * } else {
 *   // SSL 3.0 code here
 * }
