```
public ByteBuf setIndex(int readerIndex,
                        int writerIndex)
```
    Description copied from class: 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);

    Description copied from class: ByteBuf
    
    Exposes this buffer's readable bytes as an NIO ByteBuffer's. The returned buffer either share or contains the copied content of this buffer, while changing the position and limit of the returned NIO buffer does not affect the indexes and marks of this buffer. This method does not modify readerIndex or writerIndex of this buffer. Please note that the returned NIO buffer will not see the changes of this buffer if this buffer is a dynamic buffer and it adjusted its capacity.

    Description copied from class: ByteBuf
    
    Returns true if and only if this buffer has a backing byte array. If this method returns true, you can safely call ByteBuf.array() and ByteBuf.arrayOffset().
    
    Specified by:
    
    hasArray in class ByteBuf
  - array
```
public byte[] array()
```
    Description copied from class: ByteBuf
    
    Returns the backing byte array of this buffer.

    Description copied from class: ByteBuf

public long memoryAddress()
```
    Description copied from class: ByteBuf

  - isContiguous
```
public boolean isContiguous()
```
    Description copied from class: ByteBuf
    
    Returns true if this ByteBuf implementation is backed by a single memory region. Composite buffer implementations must return false even if they currently hold ≤ 1 components. For buffers that return true, it's guaranteed that a successful call to ByteBuf.discardReadBytes() will increase the value of ByteBuf.maxFastWritableBytes() by the current readerIndex.
    This method will return false by default, and a false return value does not necessarily mean that the implementation is composite or that it is not backed by a single memory region.

    Description copied from class: ByteBuf
    
    Decodes this buffer's readable bytes into a string with the specified character set name. This method is identical to buf.toString(buf.readerIndex(), buf.readableBytes(), charsetName). This method does not modify readerIndex or writerIndex of this buffer.

  - hashCode
```
public int hashCode()
```
    Description copied from class: ByteBuf
    
    Returns a hash code which was calculated from the content of this buffer. If there's a byte array which is equal to this array, both arrays should return the same value.
    
    Specified by:

  - equals
```
public boolean equals(java.lang.Object obj)
```
    Description copied from class: ByteBuf
    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 ByteBuf.readerIndex() nor ByteBuf.writerIndex(). This method also returns false for null and an object which is not an instance of ByteBuf type.

    equals in class ByteBuf
  - compareTo
```
public int compareTo(ByteBuf buffer)
```
    Description copied from class: ByteBuf
