public interface ReferenceCounted
```
A reference-counted object that requires explicit deallocation.
When a new ReferenceCounted is instantiated, it starts with the reference count of 1. retain() increases the reference count, and release() decreases the reference count. If the reference count is decreased to 0, the object will be deallocated explicitly, and accessing the deallocated object will usually result in an access violation.

If an object that implements ReferenceCounted is a container of other objects that implement ReferenceCounted, the contained objects will also be released via release() when the container's reference count becomes 0.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`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`.
`ReferenceCounted`	`touch()`	Records the current access location of this object for debugging purposes.
`ReferenceCounted`	`touch(Object hint)`	Records the current access location of this object with an additional arbitrary information for debugging purposes.

- Method Detail
  - refCnt
```
int refCnt()
```
    Returns the reference count of this object. If 0, it means this object has been deallocated.
  - retain
```
ReferenceCounted retain()
```
    Increases the reference count by 1.
  - retain
```
ReferenceCounted retain(int increment)
```
    Increases the reference count by the specified increment.
  - touch
```
ReferenceCounted touch()
```
    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).
  - touch
```
ReferenceCounted touch(Object hint)
```
    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.
  - release
```
boolean release()
```
    Decreases the reference count by 1 and deallocates this object if the reference count reaches at 0.
    
    Returns:
    
    true if and only if the reference count became 0 and this object has been deallocated
  - release
```
boolean release(int decrement)
```
    Decreases the reference count by the specified decrement and deallocates this object if the reference count reaches at 0.
    
    Returns:
    
    true if and only if the reference count became 0 and this object has been deallocated
