- Constructor Detail
  - InternalNioInputBuffer
```
public InternalNioInputBuffer(Request request,
                      int headerBufferSize,
                      boolean rejectIllegalHeader,
                      HttpParser httpParser)
```
    Alternate constructor.
- Method Detail
  - recycle
```
public void recycle()
```
    Recycle the input buffer. This should be called when closing the connection.
    
    Overrides:
    
    recycle in class AbstractInputBuffer<NioChannel>
  - nextRequest
```
public void nextRequest()
```
    End processing of current HTTP request. Note: All bytes of the current request should have been already consumed. This method only resets all the pointers so that we are ready to parse the next HTTP request.
    
    Overrides:
    
    nextRequest in class AbstractInputBuffer<NioChannel>
  - parseRequestLine
```
public boolean parseRequestLine(boolean useAvailableDataOnly)
                         throws IOException
```
    Read the request line. This function is meant to be used during the HTTP request header parsing. Do NOT attempt to read the request body using it.
    
    Specified by:
    
    parseRequestLine in class AbstractInputBuffer<NioChannel>
    
    Returns:
    true if data is properly fed; false if no data is available immediately and thread should be freed
    
    Throws:
    
    IOException - If an exception occurs during the underlying socket read operations, or if the given buffer is not big enough to accommodate the whole line.
  - parseHeaders
```
public boolean parseHeaders()
                     throws IOException
```
    Parse the HTTP headers.
    
    Specified by:
    
    parseHeaders in class AbstractInputBuffer<NioChannel>
    
    Throws:
    
    IOException
  - getParsingRequestLinePhase
```
public int getParsingRequestLinePhase()
```
  - init
```
protected void init(SocketWrapper<NioChannel> socketWrapper,
        AbstractEndpoint<NioChannel> endpoint)
             throws IOException
```
    Specified by:
    
    init in class AbstractInputBuffer<NioChannel>
    
    Throws:
    
    IOException
  - fill
```
protected boolean fill(boolean block)
                throws IOException,
                       EOFException
```
    Fill the internal buffer using data from the underlying input stream.
    
    Specified by:
    
    fill in class AbstractInputBuffer<NioChannel>
    
    Returns:
    false if at end of stream
    
    Throws:
    
    IOException
    
    EOFException
  - fill
```
protected boolean fill(boolean timeout,
           boolean block)
                throws IOException,
                       EOFException
```
    Throws:
    
    IOException
    
    EOFException
