Class FIXMessageTokenHelper

public final class FIXMessageTokenHelper
extends Object

The helper class to get information associated with a FIX message token.

Because Java doesn't support value type. We use a plain long integer to represent a FIX message token.

Use methods defined in this class to decode more detail information associated with a FIX message token, such as "Direction", "SessionPersistence" or "MsgSeqNum".

static long	NULL_TOKEN Represents a null token
