```
public Buffer readBytes(int length)
                 throws IndexOutOfBoundsException,
                        IOException
```
    Read the requested number of bytes and increase the readerIndex with the corresponding number of bytes. The new buffer and this buffer both share the same backing array so changing either one of them will affect the other.
    
    Specified by:
    
    readBytes in interface Buffer
    
    Returns:
    
    Throws:
    
    IndexOutOfBoundsException
    
    IOException
  - readLine
```
public Buffer readLine()
                throws IOException
```
    Reads a line, i.e., it reads until we hit a line feed ('\n') or a carriage return ('\r'), or a carriage return followed immediately by a line feed.
    
    Specified by:
    
    readLine in interface Buffer
    
    Returns:
    
    a buffer containing the line but without the line terminating characters
    
    Throws:
    
    IOException
  - readUntilSingleCRLF
```
public Buffer readUntilSingleCRLF()
                           throws IOException
```
    Description copied from interface: Buffer
    
    Read until we find a single CRLF. The single CRLF will NOT be part of the returned buffer but will be consumed. If we cannot find a single CRLF then null will be returned and the passed in buffer will be reset to the same reader index as when it was passed in. Note that this one is very similar to Buffer.readLine() but the readLine doesn't enforce the CRLF being present, which is typical for e.g. SIP and is important when reading bytes being streamed over e.g. a network connection
    
    Specified by:
    
    readUntilSingleCRLF in interface Buffer
    
    Returns:
    
    the resulting buffer containing everything up until (but not inclusive) the single-crlf or null if no single-crlf was not found.
    
    Throws:
    
    IOException
  - readUntilDoubleCRLF
```
public Buffer readUntilDoubleCRLF()
                           throws IOException
```
    Description copied from interface: Buffer
    
    Read until we find a double CRLF. The double CRLF will NOT be part of the returned buffer but they will be consumed. If we cannot find a double CRLF then null will be returned and the passed in buffer will be reset to the same reader index as when it was passed in.
    
    Specified by:
    
    readUntilDoubleCRLF in interface Buffer
    
    Returns:
    
    the resulting buffer containing everything up until (but not inclusive) the double-crlf or null if no double-crlf was not found.
    
    Throws:
    
    IOException
  - getReadableBytes
```
public int getReadableBytes()
```
    Returns the number of available bytes for reading without blocking. If this returns less than what you want, there may still be more bytes available depending on the underlying implementation. E.g., a Buffer backed by an InputStream may be able to read more off the stream, however, it may not be able to do so without blocking.
    
    Specified by:
    
    getReadableBytes in interface Buffer
    
    Returns:
  - hasReadableBytes
```
public boolean hasReadableBytes()
```
    Checks whether this buffer has any bytes available for reading without blocking. This is the same as Buffer.getReadableBytes() > 0
    
    Specified by:
    
    hasReadableBytes in interface Buffer
    
    Returns:
  - isEmpty
```
public boolean isEmpty()
```
    Check whether this buffer is empty or not. This is the same as !Buffer.hasReadableBytes()
    
    Specified by:
    
    isEmpty in interface Buffer
    
    Returns:
  - getArray
```
public byte[] getArray()
```
    Get the backing array.
    
    Specified by:
    
    getArray in interface Buffer
    
    Returns:
  - readUntil
```
public Buffer readUntil(byte b)
                 throws IOException,
                        ByteNotFoundException
```
    Same as #readUntil(4096, 'b') Read until the specified byte is encountered and return a buffer representing that section of the buffer. If the byte isn't found, then a ByteNotFoundException is thrown and the Buffer.getReaderIndex() is left where we bailed out. Note, the byte we are looking for will have been consumed so whatever that is left in the Buffer will not contain that byte. Example: Buffer buffer = Buffers.wrap("hello world"); Buffer hello = buffer.readUntil((byte)' '); System.out.println(hello); // will contain "hello" System.out.println(buffer); // will contain "world" As the example above illustrates, we are looking for a space, which is found between "hello" and "world". Since the space will be consumed, the original buffer will now only contain "world" and not " world".
    
    Specified by:
    
    readUntil in interface Buffer
    
    Parameters:
    
    b - the byte to look for
    
    Returns:
    
    a buffer containing the content from the initial reader index to the the position where the byte was found (exclusive the byte we are looking for)
    
    Throws:
    
    ByteNotFoundException - in case the byte we were looking for is not found.
    
    IOException
  - slice
```
public Buffer slice(int start,
                    int stop)
```
    Get a slice of the buffer starting at start (inclusive) ending at stop (exclusive). Hence, the new capacity of the buffer is stop - start
    
    Specified by:
    
    slice in interface Buffer
    
    Returns:
  - slice
```
public Buffer slice(int stop)
```
    Same as #slice(Buffer.getReaderIndex(), int)
    
    Specified by:
    
    slice in interface Buffer
    
    Returns:
  - slice
```
public Buffer slice()
```
    Slice off the rest of the buffer. Same as #slice(Buffer.getReaderIndex(), buffer.getCapacity()) Note, if you slice an empty buffer you will get back another empty buffer. Same goes for when you slice a buffer whose bytes already have been consumed.
    
    Specified by:
    
    slice in interface Buffer
    
    Returns:
  - getLowerBoundary
```
public int getLowerBoundary()
```
    Description copied from interface: Buffer
    
    If you access the Buffer.getRawArray() you will get just that. The raw un-guarded array, which may be useful but should be used with care since you now can do whatever you want with the data. However, if you do so and also want to know which 'slice' of that array this buffer is seeing, then you need to know the lower boundary as well since the array can e.g be 1k long but the data seen by this buffer starts at index 200.
    
    Specified by:
    
    getLowerBoundary in interface Buffer
    
    Returns:
  - getUpperBoundary
```
public int getUpperBoundary()
```
    Description copied from interface: Buffer
    
    See explanation in Buffer.getLowerBoundary() since this is the same, just the upper limit of that raw array.
    
    Specified by:
    
    getUpperBoundary in interface Buffer
    
    Returns:
  - getReaderIndex
```
public int getReaderIndex()
```
    The reader index
    
    Specified by:
    
    getReaderIndex in interface Buffer
    
    Returns:
  - markReaderIndex
```
public void markReaderIndex()
```
    Mark the current position of the reader index.
    
    Specified by:
    
    markReaderIndex in interface Buffer
    
    See Also:
    
    #reset()

```
public void resetReaderIndex()
```
    Reset the reader index to the marked position or to the beginning of the buffer if mark hasn't explicitly been called.
    
    Specified by:
    
    resetReaderIndex in interface Buffer

    capacity in interface Buffer
    
    Returns:
    
    the capacity
  - getByte
```
public byte getByte(int index)
             throws IndexOutOfBoundsException,
                    IOException
```
    Get the byte at the index. Note, depending on the underlying implementing buffer, this method may block and try and read the missing bytes off a stream. E.g., the InputStreamBuffer gets its bytes off of a InputStream so let's say you have read 10 bytes off of the stream already but ask to access the byte at index 20, we will try and ready an additional 10 bytes from the InputStream so we can return the byte at index 20.
    
    Specified by:
    
    getByte in interface Buffer
    
    Returns:
    
    the byte at the specified index
    
    Throws:
    
    IndexOutOfBoundsException - in case the index is greater than the capacity of this buffer
    
    IOException
  - readByte
```
public byte readByte()
              throws IndexOutOfBoundsException,
                     IOException
```
    Read the next byte, which will also increase the readerIndex by one.
    
    Specified by:
    
    readByte in interface Buffer
    
    Returns:
    
    the next byte
    
    Throws:

```
    Really nothing to clone so just return this since this EmptyBuffer is by definition immutable. Performs a deep clone of this object. I.e., the array that is backed by this buffer will be copied and a new buffer will be returned. Hence, any changes to the backing of this buffer will not affect the cloned buffer.
    
    Specified by:
    
    clone in interface Buffer
    
    Overrides:
    
    clone in class Object
    
    Returns:

                 throws IOException,
                        ByteNotFoundException
```
    Description copied from interface: Buffer
    
    Read until any of the specified bytes have been encountered or until we have read a maximum amount of bytes. This one works exactly the same as Buffer.readUntil(byte) except it allows you to look for multiple bytes and to specify for how many bytes we should be looking before we give up. Example, we want to read until we either find
    
    Specified by:
    
    readUntil in interface Buffer
    
    Parameters:
    
    maxBytes - the maximum number of bytes we would like to read before giving up.
    
    bytes - the bytes we are looking for (either one of them)
    
    Returns:
    
    a buffer containing the content from the initial reader index to the the position where the byte was found (exclusive the byte we are looking for)
    
    Throws:
    
    IOException
    
    ByteNotFoundException - in case none of the bytes we were looking for are found within the specified maximum number of bytes.
  - readUntilSafe

                     throws IOException,
                            IllegalArgumentException
```
    Description copied from interface: Buffer
    
    Same as Buffer.readUntil(int, byte...) but will return null instead of throwing a ByteNotFoundException
    
    Specified by:
    
    readUntilSafe in interface Buffer
    
    Returns:
    
    Throws:
    
    IOException
    
    IllegalArgumentException
  - indexOf
```
public int indexOf(int maxBytes,
                   byte... bytes)
            throws IOException,
                   ByteNotFoundException,
                   IllegalArgumentException
```
    Description copied from interface: Buffer
    
    Same as Buffer.readUntil(int, byte...) but instead of returning the buffer with everything up until the specified byte it returns the index instead. NOTE. The index is representing where in the Buffer you can find the byte and the index is in relation to the entire Buffer and its capacity so even if you have already read x bytes, it would not change the index of what you search for. Example:
    
    Specified by:
    
    indexOf in interface Buffer
    
    Parameters:
    
    maxBytes - the maximum number of bytes we would like to read before giving up.
    
    bytes - the bytes we are looking for (either one of them)
    
    Returns:
    
    the index of the found byte or -1 (negative one) if we couldn't find it.
    
    Throws:
    
    IOException
    
    ByteNotFoundException - will ONLY be thrown if we haven't found the byte within the maxBytes limit. If the buffer we are searching in is less than maxBytes and we can't find what we are looking for then negative one will be returned instead.
    
    IllegalArgumentException
  - indexOf
```
public int indexOf(byte b)
            throws IOException,
                   ByteNotFoundException,
