Examples of com.google.api.client.http.InputStreamContent

com.google.api.client.http.InputStreamContent
Concrete implementation of {@link AbstractInputStreamContent} that simply handles the transfer ofdata from an input stream to an output stream. This should only be used for streams that can not be re-opened and retried. If you have a stream that it is possible to recreate please create a new subclass of {@link AbstractInputStreamContent}.
The input stream is guaranteed to be closed at the end of {@link #writeTo(OutputStream)}.

Sample use with a URL:
```
  private static void setRequestJpegContent(HttpRequest request, URL jpegUrl) throws IOException { request.setContent(new InputStreamContent("image/jpeg", jpegUrl.openStream())); }  
```
Implementation is not thread-safe.
