ReasonBuffer

Helper class to create properly concatenated reason string for use in method that return String s with reasons.

If no reasons are specified #getReason() will return null , otherwise it will return a String with all the valid reasons concatenated with a semi-colon separating each one.

An alternative is to use the (very simple) Reasons class or the (much more sophisticated) ReasonBuffer2 .
