Question

I have to parse xml from the content of a Jetty buffer using SAX.
From my ContentExchange I can call getRequestContent, and then I get a Buffer

I need an InputStream, or an InputSoruce or a String or a File in order to parse it with SAX. How can I convert the buffer to one of those, and which way is the most efficient?

It looks like something obvious, but I can not find any information in the documentation.

Answer 1

Apologies for answering an old question, but someone (such as myself) may stumble upon this in the future.

Jetty’s Buffer class implements a writeTo(OutputStream) method. A simple solution would be to do the following:

PipedInputStream is = new PipedInputStream();
PipedOutputStream os = new PipedOutputStream(is);

Then for each Buffer received, do:

void processBuffer(Buffer buf) {
    buf.writeTo(os);
}

This way you can stream responses without need for caching them.

EDIT:

Of course, make sure that processBuffer() and readers of the PipedInputStream are running in separate threads to avoid potential deadlock.
