Examples of BAAOutputStream

org.apache.axiom.attachments.utils.BAAOutputStream
BAAOutputStream is like a ByteArrayOutputStream. A ByteArrayOutputStream stores the backing data in a byte[]. BAAOutputStream stores the backing data in a Array of byte[]. Using several non-contiguous chunks reduces memory copy and resizing.

Examples of org.apache.axiom.attachments.utils.BAAOutputStream

                // If this is the root part, keep it in memory.


                // Get the bytes of the data without a lot 
                // of resizing and GC.  The BAAOutputStream 
                // keeps the data in non-contiguous byte buffers.
                BAAOutputStream baaos = new BAAOutputStream();
                BufferUtils.inputStream2OutputStream(in, baaos);
                return new PartContentOnMemory(baaos.buffers(), baaos.length());
            } else {
                // We need to read the input stream to determine whether
                // the size is bigger or smaller than the threshold.
                BAAOutputStream baaos = new BAAOutputStream();
                int count = BufferUtils.inputStream2OutputStream(in, baaos, thresholdSize);


                if (count < thresholdSize) {
                    return new PartContentOnMemory(baaos.buffers(), baaos.length());
                } else {
                    // A BAAInputStream is an input stream over a list of non-contiguous 4K buffers.
                    BAAInputStream baais = 
                        new BAAInputStream(baaos.buffers(), baaos.length());

                                          baais,
