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

Constructor Summary

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

Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`MetricPlane`	`__ref__()`	Dereferencing operator.
`MetricPlaneCPtr`	`cptr()`
`void`	`delete()`
`MetricPlane`	`deref()`	The pointer stored in the object.
`double`	`distance(Plane q)`	The distance from the zero element to q
`double`	`distance(Plane a, Plane b)`	The distance from element a to b.
`boolean`	`equals(MetricPlane p)`
`static long`	`getCPtr(MetricPlanePtr obj)`
`MetricPlane`	`getDeref()`	Member access operator.
`boolean`	`isNull()`	checks if the pointer is null
`boolean`	`isShared()`	check if this Ptr has shared ownership or none ownership
`int`	`size()`	The dimension of elements on which this metric operates. The returns -1 if the elements don't have a measure of dimension or if the metric works for elements of all dimensions.
