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
