public class QStateCPtr
extends java.lang.Object
```
Ptr stores a pointer and optionally takes ownership of the value.

Constructor Summary

Constructors
Constructor	Description
`QStateCPtr()`	Default constructor yielding a NULL-pointer.
`QStateCPtr(long cPtr, boolean cMemoryOwn)`
`QStateCPtr(QState ptr)`	Do not take ownership of ptr. ptr can be null. The constructor is implicit on purpose.
