- Method Detail
  - release
```
protected void release()
                throws java.io.IOException
```
    Called when reference counting hits 0. By default this method does nothing, but extensions can override to e.g. release resources attached to object that is managed by this class.
    
    Throws:
    
    java.io.IOException
  - decRef
```
public final void decRef()
                  throws java.io.IOException
```
    Decrements the reference counting of this object. When reference counting hits 0, calls release().
    
    Throws:
    
    java.io.IOException
  - get
```
public final T get()
```
  - getRefCount
```
public final int getRefCount()
```
    Returns the current reference count.
  - incRef
```
public final void incRef()
```
    Increments the reference count. Calls to this method must be matched with calls to decRef().
