Class HttpOutput

java.lang.Object
java.io.OutputStream
jakarta.servlet.ServletOutputStream
org.eclipse.jetty.ee11.servlet.HttpOutput
All Implemented Interfaces:
Closeable, Flushable, AutoCloseable
public class HttpOutput extends jakarta.servlet.ServletOutputStream

HttpOutput implements ServletOutputStream as required by the Servlet specification.

HttpOutput buffers content written by the application until a further write will overflow the buffer, at which point it triggers a commit of the response.

HttpOutput can be closed and reopened, to allow requests included via RequestDispatcher.include(ServletRequest, ServletResponse) to close the stream, to be reopened after the inclusion ends.

  • Method Details

    • isWritten

      public boolean isWritten()
      Returns:
      True if any content has been written via the HttpServletResponse API.

    • getWritten

      public long getWritten()
      Returns:
      The bytes written via the HttpServletResponse API. This may differ from the bytes reported by Response.getContentBytesWritten(Response) due to buffering, compression, other interception or writes that bypass the servlet API.

    • setApplicationContentLength

      public void setApplicationContentLength(long len)
      Set the content-length as set by the application. This may not be the actual content length if compression or similar handlers are used.
      Parameters:
      len - The content-length as set by the application.

    • getApplicationContentLength

      public long getApplicationContentLength()
      Get the content-length as set by the application. This may not be the actual content length if compression or similar handlers are used.
      Returns:
      The content-length as set by the application.

    • isContentIncomplete

      public boolean isContentIncomplete()
      Returns:
      true if a Content-Length has been set and insufficient content has been written.

    • reopen

      public void reopen()

    • softClose

      public void softClose()

    • takeContentAndClose

      public ByteBuffer takeContentAndClose()

    • complete

      public void complete(Callback callback)
      This method is invoked for the COMPLETE action handling in HttpChannel.handle. The callback passed typically will call completed to finish the request cycle and so may need to asynchronously wait for: a pending/blocked operation to finish and then either an async close or wait for an application close to complete.
      Parameters:
      callback - The callback to complete when writing the output is complete.

    • completed

      public void completed(Throwable ignored)
      Called to indicate that the request cycle has been completed.
