- Method Detail
  - 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<Socket>
    
    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<Socket>
    
    Throws:
    
    IOException
  - recycle
```
public void recycle()
```
    Description copied from class: AbstractInputBuffer
    
    Recycle the input buffer. This should be called when closing the connection.
    
    Overrides:
    
    recycle in class AbstractInputBuffer<Socket>
  - init

protected void init(SocketWrapper<Socket> socketWrapper,
        AbstractEndpoint<Socket> endpoint)
             throws IOException
```
    Specified by:
    
    init in class AbstractInputBuffer<Socket>
    
    Throws:

                throws IOException
```
    Fill the internal buffer using data from the underlying input stream.
    
    Returns:
    false if at end of stream
    
    Throws:
