```
public InternalAprInputBuffer(Request request,
                      int headerBufferSize)
```
    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<java.lang.Long>
  - parseRequestLine
```
public boolean parseRequestLine(boolean useAvailableData)
                         throws java.io.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<java.lang.Long>
    
    Returns:
    true if data is properly fed; false if no data is available immediately and thread should be freed
    
    Throws:
    
    java.io.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 java.io.IOException
```
    Parse the HTTP headers.
    
    Specified by:
    
    parseHeaders in class AbstractInputBuffer<java.lang.Long>
    
    Throws:
    
    java.io.IOException
  - doRead
```
public int doRead(ByteChunk chunk,
         Request req)
           throws java.io.IOException
```
    Read some bytes.
    
    Specified by:
    
    doRead in interface InputBuffer
    
    Overrides:
    
    doRead in class AbstractInputBuffer<java.lang.Long>
    
    Throws:
    
    java.io.IOException

    Throws:
    
    java.io.IOException
  - fill
```
protected boolean fill()
                throws java.io.IOException
```
    Fill the internal buffer using data from the underlying input stream.
