  - content
```
ByteBuf content()
```
    Return the data which is held by this ByteBufHolder.
  - copy
```
ByteBufHolder copy()
```
    Creates a deep copy of this ByteBufHolder.
  - duplicate
```
ByteBufHolder duplicate()
```
    Duplicates this ByteBufHolder. Be aware that this will not automatically call retain().
  - retainedDuplicate
```
ByteBufHolder retainedDuplicate()
```
    Duplicates this ByteBufHolder. This method returns a retained duplicate unlike duplicate().

    ByteBuf.retainedDuplicate()
  - replace
```
ByteBufHolder replace(ByteBuf content)
```
    Returns a new ByteBufHolder which contains the specified content.
  - retain
```
ByteBufHolder retain()
```
    Description copied from interface: ReferenceCounted
    
    Increases the reference count by 1.

    retain in interface ReferenceCounted
  - touch
```
ByteBufHolder touch()
```
    Description copied from interface: 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).
