    capacity in interface ByteBuf
  - readerIndex
```
CompositeByteBuf readerIndex(int readerIndex)

  - writerIndex

  - setIndex
```
CompositeByteBuf setIndex(int readerIndex,
                        int writerIndex)
```
    Description copied from interface: ByteBuf
    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 ByteBuf.readerIndex(int) and ByteBuf.writerIndex(int) methods. For example, the following code will fail:
```
 // Create a buffer whose readerIndex, writerIndex and capacity are
 // 0, 0 and 8 respectively.
 ByteBuf buf = Unpooled.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.
 ByteBuf buf = Unpooled.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, this method 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);
 
```
    Specified by:
    
    setIndex in interface ByteBuf
  - clear
```
CompositeByteBuf clear()
```
    Description copied from interface: ByteBuf
    
    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.
    
    Specified by:
    
    clear in interface ByteBuf
  - markReaderIndex
```
CompositeByteBuf markReaderIndex()
```

    markReaderIndex in interface ByteBuf
  - resetReaderIndex
```

```

  - discardReadBytes
```
CompositeByteBuf discardReadBytes()
```
    Description copied from interface: ByteBuf
    
    Discards the bytes between the 0th index and readerIndex. It moves the bytes between readerIndex and writerIndex to the 0th index, and sets readerIndex and writerIndex to 0 and oldWriterIndex - oldReaderIndex respectively.

```
    Description copied from interface: ByteBuf
