- Method Detail
  - setRequest
```
void setRequest(Request request)
```
    Some filters need additional parameters from the request.
    
    Parameters:
    
    request - The request to be associated with this filter
  - recycle
```
void recycle()
```
    Make the filter ready to process the next request.
  - getEncodingName
```
ByteChunk getEncodingName()
```
    Get the name of the encoding handled by this filter.
    
    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
```
void setBuffer(InputBuffer buffer)
```
    Set the next buffer in the filter pipeline.
    
    Parameters:
    
    buffer - The next buffer
  - end
```
long end()
  throws java.io.IOException
```
    End the current request.
    
    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
```
boolean isFinished()
```
    Has the request body been read fully?
    
    Returns:
    
    true if the request body has been fully read, otherwise false
