Constructor and Description
`InternalInputBuffer(Request request, int headerBufferSize, boolean rejectIllegalHeaderName, HttpParser httpParser)` Default constructor.

Method Summary

Methods
Modifier and Type	Method and Description
`int`	`available(boolean read)` Data is always available for blocking IO (if you wait long enough) so return a value of 1.
`protected boolean`	`fill()` Fill the internal buffer using data from the underlying input stream.
`protected boolean`	`fill(boolean block)` Attempts to read some data into the input buffer.
`protected Log`	`getLog()`
`protected void`	`init(SocketWrapper<java.net.Socket> socketWrapper, AbstractEndpoint<java.net.Socket> endpoint)`
`boolean`	`parseHeaders()` Parse the HTTP headers.
`boolean`	`parseRequestLine(boolean useAvailableDataOnly)` Read the request line.
`void`	`recycle()` Recycle the input buffer.

public InternalInputBuffer(Request request,
                   int headerBufferSize,
                   boolean rejectIllegalHeaderName,
                   HttpParser httpParser)
```
    Default constructor.
- Method Detail
  - available
```
public int available(boolean read)
```
    Data is always available for blocking IO (if you wait long enough) so return a value of 1. Note that the actual value is never used it is only tested for == 0 or > 0.
    
    Overrides:
    
    available in class AbstractInputBuffer<java.net.Socket>
  - parseRequestLine
```
public boolean parseRequestLine(boolean useAvailableDataOnly)
                         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.net.Socket>
    
    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.net.Socket>
    
    Throws:
    
    java.io.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<java.net.Socket>
  - init
```
protected void init(SocketWrapper<java.net.Socket> socketWrapper,
        AbstractEndpoint<java.net.Socket> endpoint)
             throws java.io.IOException
```
    Specified by:
    
    init in class AbstractInputBuffer<java.net.Socket>
    
    Throws:
    
    java.io.IOException
  - fill
```
protected boolean fill()
                throws java.io.IOException
```
    Fill the internal buffer using data from the underlying input stream.
    
    Returns:
    false if at end of stream
    
    Throws:
    
    java.io.IOException
  - fill
```
protected boolean fill(boolean block)
                throws java.io.IOException
```
    Description copied from class: AbstractInputBuffer
    
    Attempts to read some data into the input buffer.
    
    Specified by:
    
    fill in class AbstractInputBuffer<java.net.Socket>
    
    Returns:
    true if more data was added to the input buffer otherwise false
    
    Throws:
    
    java.io.IOException
  - getLog
```
protected final Log getLog()
```
    Specified by:
    
    getLog in class AbstractInputBuffer<java.net.Socket>
