Class SavedRequestInputFilter

  • All Implemented Interfaces:
    InputFilter, InputBuffer
    public class SavedRequestInputFilter
extends Object
implements InputFilter
    Input filter responsible for replaying the request body when restoring the saved request after FORM authentication.

    • Field Detail

      • input

        protected ByteChunk input
        The original request body.

    • Constructor Detail

      • SavedRequestInputFilter

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

    • Method Detail

      • doRead

        public int doRead​(ApplicationBufferHandler handler)
           throws 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:
        IOException - If an I/O error occurs reading from the input stream

      • setRequest

        public void setRequest​(Request 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()
        Make the filter ready to process the next request.
        Specified by:
        recycle in interface InputFilter

      • getEncodingName

        public ByteChunk getEncodingName()
        Return the name of the associated encoding; here, the value is null.
        Specified by:
        getEncodingName in interface InputFilter
        Returns:
        The encoding name as a byte chunk to facilitate comparison with the value read from the HTTP headers which will also be a ByteChunk

      • 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 - The next buffer

      • available

        public int available()
        Amount of bytes still available in a buffer.
        Specified by:
        available in interface InputBuffer
        Returns:
        The number of bytes that can be read without blocking

      • end

        public long end()
         throws IOException
        End the current request (has no effect).
        Specified by:
        end in interface InputFilter
        Returns:
        0 is the expected return value. A positive value indicates that too many bytes were read. This method is allowed to use buffer.doRead to consume extra bytes. The result of this method can't be negative (if an error happens, an IOException should be thrown instead).
        Throws:
        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
