      Modifier and Type Method Description
      int available()
      Obtain an estimate of the number of bytes that can be read without blocking.
      int doRead​(ApplicationBufferHandler handler)
      Read from the input stream into the ByteBuffer provided by the ApplicationBufferHandler.
      long end()
      End the current request (has no effect).
      ByteChunk getEncodingName()

      • SavedRequestInputFilter

        public SavedRequestInputFilter​(ByteChunk input)
        Create a new SavedRequestInputFilter.
        Parameters:
        input - The saved request body to be replayed.

      • doRead

        public int doRead​(ApplicationBufferHandler handler)
           throws java.io.IOException
        Description copied from interface: InputBuffer
        Read from the input stream into the ByteBuffer provided by the ApplicationBufferHandler. IMPORTANT: the current model assumes that the protocol will 'own' the ByteBuffer and return a pointer to it.
        Specified by:
        doRead in interface InputBuffer
        Parameters:
        handler - ApplicationBufferHandler that provides the buffer to read data into.
        Returns:
        The number of bytes that have been added to the buffer or -1 for end of stream
        Throws:
        java.io.IOException - If an I/O error occurs reading from the input stream

      • setRequest

        public void setRequest​(Request request)
        Some filters need additional parameters from the request. Set the content length on the request.
        Specified by:
        setRequest in interface InputFilter
        Parameters:
        request - The request to be associated with this filter

      • recycle

        public void recycle()
        Description copied from interface: InputFilter
        Make the filter ready to process the next request.
        Specified by:
        recycle in interface InputFilter

      • setBuffer

        public void setBuffer​(InputBuffer buffer)
        Set the next buffer in the filter pipeline (has no effect).
        Specified by:
        setBuffer in interface InputFilter
        Parameters:
        buffer - ignored

      • available

        public int available()
        Description copied from interface: InputBuffer
        Obtain an estimate of the number of bytes that can be read without blocking. Typically, this will be the number of available bytes known to be buffered.
        Specified by:
        available in interface InputBuffer
        Returns:
        The number of bytes that can be read without blocking

      • end

        public long end()
         throws java.io.IOException
        End the current request (has no effect).
        Specified by:
        end in interface InputFilter
        Returns:
        0
        Throws:
        java.io.IOException - If an error happens

      • isFinished

        public boolean isFinished()
        Description copied from interface: InputFilter
        Has the request body been read fully?
        Specified by:
        isFinished in interface InputFilter
        Returns:
        true if the request body has been fully read, otherwise false
