Examples of org.apache.axiom.util.blob.OverflowBlob$InputStreamImpl

org.apache.axiom.util.blob.OverflowBlob
Blob implementation that stores data in a temporary file if the size exceeds a configurable threshold. The data is first stored into a fixed size buffer. Once this buffer overflows, it is transferred to a temporary file. The buffer is divided into a given number of fixed size chunks that are allocated on demand. Since a temporary file may be created it is mandatory to call {@link #release()} to discard the blob.

     * Write the stream to a temporary storage and calculate the content length
     * @param entity HTTPEntity
     * @throws IOException if an exception occurred while writing data
     */
    private void setStreamAsTempData(BasicHttpEntity entity) throws IOException {
        OverflowBlob serialized = new OverflowBlob(256, 4096, "http-nio_", ".dat");
        OutputStream out = serialized.getOutputStream();
        try {
            messageFormatter.writeTo(msgContext, format, out, true);
        } finally {
            out.close();
        }
        msgContext.setProperty(NhttpConstants.SERIALIZED_BYTES, serialized);
        entity.setContentLength(serialized.getLength());
