Re: [Webmacro-devel] Re: [Melati-developers] WebMacro Test Case: TestSharedOutputStream

[Keats <ke...@xa...>]

There probably should be a more straightforward way to get at the FastWriter
than what I outlined, but I have a hard time thinking of a good use-case to
justify this.  Dumping a megabyte of dynamic text into a Web page seems a
bit extreme.  WebMacro was designed to cache all output before writing it
out.  If this isn't appropriate for a particular application, maybe WM isn't
the right tool for that application.

However, having said this, I'm all in favor of making the system flexible.
You could, of course, implement your own subclass of FastWriter that doesn't
cache and put a reference to that into the context.  Something like a
FastWriterOutputStreamAdapter.  Maybe we should provide something like this
with an UnbufferedWMServlet example.
