```
public DefaultByteBufHolder(ByteBuf data)
```
- 方法详细资料
  - content
```
public ByteBuf content()
```
    从接口复制的说明: ByteBufHolder
    
    Return the data which is held by this ByteBufHolder.
    
    指定者:
    
    content 在接口中 ByteBufHolder
  - copy
```
public ByteBufHolder copy()
```
    Creates a deep copy of this ByteBufHolder.
    This method calls replace(content().copy()) by default.
    
    指定者:
    
    copy 在接口中 ByteBufHolder
  - duplicate
```
public ByteBufHolder duplicate()
```
    Duplicates this ByteBufHolder. Be aware that this will not automatically call ByteBufHolder.retain().
    This method calls replace(content().duplicate()) by default.
    
    指定者:
    
    duplicate 在接口中 ByteBufHolder
  - retainedDuplicate
```
public ByteBufHolder retainedDuplicate()
```
    Duplicates this ByteBufHolder. This method returns a retained duplicate unlike ByteBufHolder.duplicate().
    This method calls replace(content().retainedDuplicate()) by default.
    
    指定者:
    
    retainedDuplicate 在接口中 ByteBufHolder
    
    另请参阅:
    
    ByteBuf.retainedDuplicate()
  - replace
```
public ByteBufHolder replace(ByteBuf content)
```
    Returns a new ByteBufHolder which contains the specified content.
    Override this method to return a new instance of this object whose content is set to the specified content. The default implementation of copy(), duplicate() and retainedDuplicate() invokes this method to create a copy.
    
    指定者:
    
    replace 在接口中 ByteBufHolder
  - 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.
    
    指定者:
    
    refCnt 在接口中 ReferenceCounted
  - retain
```
public ByteBufHolder retain()
```
    从接口复制的说明: ReferenceCounted
    
    Increases the reference count by 1.
    
    指定者:
    
    retain 在接口中 ByteBufHolder
    
    指定者:
    
    retain 在接口中 ReferenceCounted
  - retain
```
public ByteBufHolder 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 ByteBufHolder
    
    指定者:
    
    retain 在接口中 ReferenceCounted
  - touch
```
public ByteBufHolder touch()
```
    从接口复制的说明: ReferenceCounted
    
    Records the current access location of this object for debugging purposes. If this object is determined to be leaked, the information recorded by this operation will be provided to you via ResourceLeakDetector. This method is a shortcut to touch(null).
    
    指定者:
    
    touch 在接口中 ByteBufHolder
    
    指定者:
    
    touch 在接口中 ReferenceCounted
  - touch
```
public ByteBufHolder touch(java.lang.Object hint)
```
    从接口复制的说明: ReferenceCounted
    
    Records the current access location of this object with an additional arbitrary information for debugging purposes. If this object is determined to be leaked, the information recorded by this operation will be provided to you via ResourceLeakDetector.
    
    指定者:
    
    touch 在接口中 ByteBufHolder
    
    指定者:
    
    touch 在接口中 ReferenceCounted
  - 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.
    
    指定者:
    
    release 在接口中 ReferenceCounted
    
    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.
    
    指定者:
    
    release 在接口中 ReferenceCounted
    
    返回:
    
    true if and only if the reference count became 0 and this object has been deallocated
  - contentToString
```
protected final java.lang.String contentToString()
```
    Return ByteBuf.toString() without checking the reference count first. This is useful to implement toString().
  - toString
```
public java.lang.String toString()
```
    覆盖:
    
    toString 在类中 java.lang.Object
  - equals
```
public boolean equals(java.lang.Object o)
```
    This implementation of the equals operation is restricted to work only with instances of the same class. The reason for that is that Netty library already has a number of classes that extend DefaultByteBufHolder and override equals method with an additional comparison logic and we need the symmetric property of the equals operation to be preserved.
    
    覆盖:
    
    equals 在类中 java.lang.Object
    
    参数:
    
    o - the reference object with which to compare.
    
    返回:
    
    true if this object is the same as the obj argument; false otherwise.
  - hashCode
```
public int hashCode()
```
    覆盖:
    
    hashCode 在类中 java.lang.Object
