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

Method Detail
-
doRead
public int doRead(ApplicationBufferHandler handler) throws java.io.IOException
Description copied from interface:InputBufferRead 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:
doReadin interfaceInputBuffer- 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)
Set the content length on the request.- Specified by:
setRequestin interfaceInputFilter- 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:
recyclein interfaceInputFilter
-
getEncodingName
public ByteChunk getEncodingName()
Return the name of the associated encoding; here, the value is null.- Specified by:
getEncodingNamein interfaceInputFilter- 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:
setBufferin interfaceInputFilter- Parameters:
buffer- The next buffer
-
available
public int available()
Amount of bytes still available in a buffer.- Specified by:
availablein interfaceInputBuffer- Returns:
- The number of bytes that can be read without blocking
-
end
public long end() throws java.io.IOExceptionEnd the current request (has no effect).- Specified by:
endin interfaceInputFilter- 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:
java.io.IOException- If an error happens
-
isFinished
public boolean isFinished()
Description copied from interface:InputFilterHas the request body been read fully?- Specified by:
isFinishedin interfaceInputFilter- Returns:
trueif the request body has been fully read, otherwisefalse
