Hi Alex, 
 
I'm sorry to reply so late -- I've been without access to email for the last
few days.  
 
To see how many repetitions of a segment exist, you can do
group.getAll(String name) (which returns an array) and check its length
property.  The equivalent for fields is segment.getField(int fieldNumber).
Does that do it?

Subject: [HAPI-devel] working with AbstractGroup


I've not been able to discover from the documentation how to determine how
many repetitions of a given field exist in a message. For instance, in many
of the A messages the IN1 and IN2 fields may repeat any number of times. I'm
unable to tell how many groups of these exist in a given message without
catching an exception. I'm sure I am missing something obvious.
 
Thanks,
