RE: [HAPI-devel] message segment counts

[abraham t. <ti...@ta...>]

Like this one:

(RXC[]) group.getAll("RXC")

yes, this one is better, pure for sure: 

RXC[] getAllRXC();

But an inbetween solution _might_ be:

group.getAll(RXC.class);

this would allow some overloading, and help out in certain cases where
there are DEFINITELY supposed to be or DEFINITELY NOT supposed to be
certain segments in a type of message.

Yes, the brute-force method of avoiding name collisions.  This is how
group
names were originally defined in the XML encoding.  For example the
corresponding DTD element for this group was: 

<!ENTITY % RDE_O01.ORCRXONTERXRRXCNTERXERXRRXCOBXNTECTI.CONTENT
(ORC,RDE_O01.RXONTERXRRXCNTE?,RXE,RXR+,RXC*,RDE_O01.OBXNTE+,CTI*)"> 

More recently HL7 has been coming up with nice, short group names, so
this
won't last forever.

I would do this: 

(RXC[]) group.getAll("RXC");

... but come to think of it this doesn't test your assumptions about
message
structure at compile time.  Maybe there should also be: 

RXC[] getAllRXC();

... or: 

int getNumRXC();

What does everyone think?  

Thanks, 
Bryan
