Function Details

iterStanChunked(stan, ctx, chunkSize)

source code

yields strings made from stan.

This is basically like iterflatten, but it doesn't accumulate as much material in strings. We need this here since stock nevow iterflatten will block the server thread of extended periods of time (say, several seconds) on large HTML tables.

Note that deferreds are not really supported (i.e., if you pass in deferreds, they must already be ready).
