public class Contact2DPtr
extends java.lang.Object
```
Ptr stores a pointer and optionally takes ownership of the value.

Constructor Summary

Constructor	Description
`Contact2DPtr()`	Default constructor yielding a NULL-pointer.
`Contact2DPtr(long cPtr, boolean cMemoryOwn)`
`Contact2DPtr(Contact2D ptr)`	Do not take ownership of ptr. ptr can be null. The constructor is implicit on purpose.
