Detailed Description

Encapsulates operations over FIX Repeating Group.

Repeating group represents array of repeating group instances, So, class exposes corresponding services to manipulate array of repeating group instances. Similar to the GroupInstance it behaves like a pointer/reference to the underlying data. It's a light-weight object which just wraps internal data.

Group remains valid until corresponding field (which defines size/length of repeating group) from field-set (message or outer repeating group instance) is updated.
