What should an AudioFileReader.getAudioInputStream(InputStream)*
do/throw when it encounters an unrecognized stream?

The JavaDocs declare that it throws an UnsupportedAudioFileException.

* <http://java.sun.com/javase/6/docs/ap...d/sampled/spi/
AudioFileReader.html#getAudioInputStream(java.io.I nputStream)>

I am developing a new sound format. After some months of wrangling
with the build tools to get an app. that correctly registers a new
audio
type via the ServiceProvider interface (fixed in the end, by upgrading
to
the latest version of Ant), I am now puzzling over what to do when
the
new class is handed an audio stream that is handled by one of the
*pre-existing* formats.

If I throw an UnsupportedAudioFileException when handed a format
that is not the new one, the app. can no longer read existing formats.
If I fail to throw an UAFE, my class is left trying to deal with data
for which it was not designed, and cannot cope.

Anybody encountered this before / have any tips on how to proceed?

I haven't tried it, but I'd expect AudioSystem to try-catch-iterate over
the registered providers (at least, if a File, URL or InputStream is given).

I'd have thought so as well, but throwing
an UAFE within my own reader stops the
process, whatever that process is.

...Now I look at the source for
AudioSystem.getAudioInputStream(InputStream)
it supports what you are saying, it iterates
a list of the AudioFileReaders, try/catching
on UAFE!

I'll think some more on where /I/ am going
wrong with that process..
