PIPE processing for large products

If I call a processing routine via 'PIPE -close' in pqact.conf, am I guarenteed that my 'decoder' is only invoked once, no matter what the size of the product?

I'd like to know that when my decoder gets end-of-file from the pipe that the entire product is available. This would allow my decoder to invoke other processing on the completed file.

Thanks!
