public void setIndex(int readerIndex,
                     int writerIndex)
```
    Description copied from interface: ChannelBuffer
    Sets the readerIndex and writerIndex of this buffer in one shot. This method is useful when you have to worry about the invocation order of ChannelBuffer.readerIndex(int) and ChannelBuffer.writerIndex(int) methods. For example, the following code will fail:
```
 // Create a buffer whose readerIndex, writerIndex and capacity are
 // 0, 0 and 8 respectively.
 ChannelBuffer buf = ChannelBuffers.buffer(8);

 // IndexOutOfBoundsException is thrown because the specified
 // readerIndex (2) cannot be greater than the current writerIndex (0).
 buf.readerIndex(2);
 buf.writerIndex(4);
 
```
    The following code will also fail:
```
 // Create a buffer whose readerIndex, writerIndex and capacity are
 // 0, 8 and 8 respectively.
 ChannelBuffer buf = ChannelBuffers.wrappedBuffer(new
 byte[8]);

 // readerIndex becomes 8.
 buf.readLong();

 // IndexOutOfBoundsException is thrown because the specified
 // writerIndex (4) cannot be less than the current readerIndex (8).
 buf.writerIndex(4);
 buf.readerIndex(2);
 
```
    By contrast, ChannelBuffer.setIndex(int, int) guarantees that it never throws an IndexOutOfBoundsException as long as the specified indexes meet basic constraints, regardless what the current index values of the buffer are:
```
 // No matter what the current state of the buffer is, the following
 // call always succeeds as long as the capacity of the buffer is not
 // less than 4.
 buf.setIndex(2, 4);
 
```

```
public void clear()
```
    Description copied from interface: ChannelBuffer
    
    Sets the readerIndex and writerIndex of this buffer to 0. This method is identical to setIndex(0, 0).
    Please note that the behavior of this method is different from that of NIO buffer, which sets the limit to the capacity of the buffer.

  - ensureWritableBytes
```
public void ensureWritableBytes(int writableBytes)
```
    Description copied from interface: ChannelBuffer
    Makes sure the number of the writable bytes is equal to or greater than the specified value. If there is enough writable bytes in this buffer, this method returns with no side effect. Otherwise:
    - a non-dynamic buffer will throw an IndexOutOfBoundsException.
    - a dynamic buffer will expand its capacity so that the number of the writable bytes becomes equal to or greater than the specified value. The expansion involves the reallocation of the internal buffer and consequently memory copy.

    Description copied from interface: ChannelBuffer
    
    Returns a copy of this buffer's readable bytes. Modifying the content of the returned buffer or this buffer does not affect each other at all. This method is identical to buf.copy(buf.readerIndex(), buf.readableBytes()). This method does not modify readerIndex or writerIndex of this buffer.

public ByteBuffer toByteBuffer()
```
    Description copied from interface: ChannelBuffer
    
    Converts this buffer's readable bytes into a NIO buffer. The returned buffer might or might not share the content with this buffer, while they have separate indexes and marks. This method is identical to buf.toByteBuffer(buf.readerIndex(), buf.readableBytes()). This method does not modify readerIndex or writerIndex of this buffer.

  - equals
```
public boolean equals(Object o)
```
    Description copied from interface: ChannelBuffer
    Determines if the content of the specified buffer is identical to the content of this array. 'Identical' here means:
    - the size of the contents of the two buffers are same and
    - every single byte of the content of the two buffers are same.
    Please note that it does not compare ChannelBuffer.readerIndex() nor ChannelBuffer.writerIndex(). This method also returns false for null and an object which is not an instance of ChannelBuffer type.
