Class BufferedResponseHandler

  • All Implemented Interfaces:
    Handler, HandlerContainer, Container, Destroyable, Dumpable, Dumpable.DumpableContainer, LifeCycle
    Direct Known Subclasses:
    FileBufferedResponseHandler
    public class BufferedResponseHandler
extends HandlerWrapper

    A Handler that can apply a HttpOutput.Interceptor mechanism to buffer the entire response content until the output is closed. This allows the commit to be delayed until the response is complete and thus headers and response status can be changed while writing the body.

    Note that the decision to buffer is influenced by the headers and status at the first write, and thus subsequent changes to those headers will not influence the decision to buffer or not.

    Note also that there are no memory limits to the size of the buffer, thus this handler can represent an unbounded memory commitment if the content generated can also be unbounded.
