    从类复制的说明: 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);

```
    从类复制的说明: ByteBuf
    
    Exposes this buffer's bytes as an NIO ByteBuffer's for the specified index and length 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.

  - refCnt
```
public int refCnt()
```
    从接口复制的说明: ReferenceCounted
    
    Returns the reference count of this object. If 0, it means this object has been deallocated.
  - retain
```
public ByteBuf retain()
```
    从接口复制的说明: ReferenceCounted
    
    Increases the reference count by 1.
    
    指定者:

```
public ByteBuf retain(int increment)
```
    从接口复制的说明: ReferenceCounted
    
    Increases the reference count by the specified increment.
    
    指定者:
    
    retain 在接口中 ReferenceCounted
    
    指定者:
    
    retain 在类中 ByteBuf
  - release
```
public boolean release()
```
    从接口复制的说明: ReferenceCounted
    
    Decreases the reference count by 1 and deallocates this object if the reference count reaches at 0.
    
    返回:
    true if and only if the reference count became 0 and this object has been deallocated
  - release
```
public boolean release(int decrement)
```
    从接口复制的说明: ReferenceCounted
    
    Decreases the reference count by the specified decrement and deallocates this object if the reference count reaches at 0.
    
    返回:
    true if and only if the reference count became 0 and this object has been deallocated
  - hashCode
```
public int hashCode()
```
    从类复制的说明: 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.
    
    指定者:
    
    hashCode 在类中 ByteBuf
  - equals
```
public boolean equals(java.lang.Object obj)
```
    从类复制的说明: 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.
    指定者:
    
    equals 在类中 ByteBuf
  - compareTo
```
public int compareTo(ByteBuf buffer)
```
    从类复制的说明: ByteBuf
    
    Compares the content of the specified buffer to the content of this buffer. Comparison is performed in the same manner with the string comparison functions of various languages such as strcmp, memcmp and String.compareTo(String).
    
    指定者:
    
    compareTo 在接口中 java.lang.Comparable<ByteBuf>
    
    指定者:
    
    compareTo 在类中 ByteBuf
  - toString
```
public java.lang.String toString()
```
    从类复制的说明: ByteBuf
    
    Returns the string representation of this buffer. This method does not necessarily return the whole content of the buffer but returns the values of the key properties such as ByteBuf.readerIndex(), ByteBuf.writerIndex() and ByteBuf.capacity().
