Class SavedRequestInputFilter

java.lang.Object
org.apache.coyote.http11.filters.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 Details

    • input

      protected ByteChunk input
      The original request body.

  • Constructor Details

    • SavedRequestInputFilter

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

  • Method Details

    • 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
