Method Details

render

public void render(OutputStream stream,
 com.yahoo.jdisc.handler.ContentChannel channel,
 com.yahoo.jdisc.handler.CompletionHandler completionHandler)
            throws IOException

Description copied from class: AsyncHttpResponse

Render to output asynchronously. The output stream will not be closed when this return. The implementation is responsible for closing the output (using the provided channel and completion handler) when (async) rendering is completed.

Specified by:

render in class AsyncHttpResponse

Parameters:

stream - the stream to which content should be rendered

channel - the channel which must be closed on completion

completionHandler - the completion handler to submit when closing the channel, may be null

Throws:

IOException

getContentType

public String getContentType()

Description copied from class: HttpResponse

The MIME type of the response contents or null. If null is returned, no content type header is added to the HTTP response.

Overrides:

getContentType in class HttpResponse

Returns:

by default HttpResponse.DEFAULT_MIME_TYPE

getCharacterEncoding

public String getCharacterEncoding()

Description copied from class: HttpResponse

The name of the encoding for the response contents, if applicable. Return null if character set is not applicable to the response in question (e.g. binary formats). If null is returned, not "charset" element is added to the content type header.

Overrides:

getCharacterEncoding in class HttpResponse

Returns:

by default HttpResponse.DEFAULT_CHARACTER_ENCODING

complete

public void complete()

Description copied from class: HttpResponse

Complete creation of this response. This is called by the container once just before writing the response header back to the caller, so this is the last moment at which status and headers can be determined. This default implementation does nothing.

Overrides:

complete in class HttpResponse

getLogValues

public Iterable<Execution.Trace.LogValue> getLogValues()

Overrides:

getLogValues in class HttpResponse
