Constant Field Values

ENCODING

protected static final ByteChunk ENCODING

contentLength

protected long contentLength

remaining

protected long remaining
Remaining bytes.


buffer

protected InputBuffer buffer
Next buffer in the pipeline.

protected ByteChunk endChunk
Chunk used to read leftover bytes.

Constructor Detail

IdentityInputFilter

public IdentityInputFilter()
Method Detail

getContentLength

public long getContentLength()
Get content length.


getRemaining

public long getRemaining()
Get remaining bytes.


doRead

public int doRead(ByteChunk chunk,
                  Request req)
           throws java.io.IOException
Read bytes.

Specified by:
doRead in interface InputFilter
Specified by:
doRead in interface InputBuffer
Returns:
If the filter does request length control, this value is significant; it should be the number of bytes consumed from the buffer, up until the end of the current request body, or the buffer length, whichever is greater. If the filter does not do request body length control, the returned value should be -1.
Throws:
java.io.IOException

setRequest

public void setRequest(Request request)
Read the content length from the request.

Specified by:
setRequest in interface InputFilter

end

public long end()
         throws java.io.IOException
Description copied from interface: InputFilter
End the current request.

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:
java.io.IOException

available

public int available()
Amount of bytes still available in a buffer.

Specified by:
available in interface InputFilter

setBuffer

public void setBuffer(InputBuffer buffer)
Set the next buffer in the filter pipeline.

Specified by:
setBuffer in interface InputFilter

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 "identity".

Specified by:
getEncodingName in interface InputFilter
