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

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