query or cf array to/from a thinArray ( a special-format, delimited
list ). The thinArray can then be transmitted to/from a web service as
a single string within an XML (WDDX) packet. It has the additional
advantage of reducing bandwidth (XML tag overhead from about 256% to
9%)
You would need to write the equivalent functions on the net side in
whatever language you choose. But that should not be too difficult as
you could just re-implement the logic in the CFC -- it is almost
trivial:
Rob Rohan has implemented _javascript_ thinArray processing in his
Neuromancer package at:
http://www.rohanclan.com/products/neuromancer/
The thinArray CFC (cfBAM.cfc) is part of the package. The
documentation is in comments at the start of the CFC.
