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

Constructor Summary

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