Method Summary

All Methods Instance Methods Abstract Methods Concrete Methods
Modifier and Type	Method	Description
`protected abstract void`	`deallocate()`	Called once `refCnt()` is equals 0.
`int`	`refCnt()`	Returns the reference count of this object.
`boolean`	`release()`	Decreases the reference count by `1` and deallocates this object if the reference count reaches at `0`.
`boolean`	`release(int decrement)`	Decreases the reference count by the specified `decrement` and deallocates this object if the reference count reaches at `0`.
`ReferenceCounted`	`retain()`	Increases the reference count by `1`.
`ReferenceCounted`	`retain(int increment)`	Increases the reference count by the specified `increment`.
`protected void`	`setRefCnt(int refCnt)`	An unsafe operation intended for use by a subclass that sets the reference count of the buffer directly
`ReferenceCounted`	`touch()`	Records the current access location of this object for debugging purposes.

  - refCnt
```
public int refCnt()
```
    Description copied from interface: ReferenceCounted
    
    Returns the reference count of this object. If 0, it means this object has been deallocated.
    
    Specified by:
    
    refCnt in interface ReferenceCounted
  - setRefCnt
```
protected final void setRefCnt(int refCnt)
```
    An unsafe operation intended for use by a subclass that sets the reference count of the buffer directly
  - retain
```
public ReferenceCounted retain()
```
    Description copied from interface: ReferenceCounted
    
    Increases the reference count by 1.
    
    Specified by:
    
    retain in interface ReferenceCounted
  - retain
```
public ReferenceCounted retain(int increment)
```
    Description copied from interface: ReferenceCounted
    
    Increases the reference count by the specified increment.
    
    Specified by:
    
    retain in interface ReferenceCounted
  - touch
```
public ReferenceCounted 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).
    
    Specified by:
    
    touch in interface ReferenceCounted
  - release
```
public boolean release()
```
    Description copied from interface: ReferenceCounted
    
    Decreases the reference count by 1 and deallocates this object if the reference count reaches at 0.
    
    Specified by:
    
    release in interface ReferenceCounted
    
    Returns:
    
    true if and only if the reference count became 0 and this object has been deallocated
  - release
```
public boolean release(int decrement)
```
    Description copied from interface: ReferenceCounted
    
    Decreases the reference count by the specified decrement and deallocates this object if the reference count reaches at 0.
    
    Specified by:
    
    release in interface ReferenceCounted
    
    Returns:
    
    true if and only if the reference count became 0 and this object has been deallocated
  - deallocate
```
protected abstract void deallocate()
```
    Called once refCnt() is equals 0.
