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

Constructor Summary

Constructors
Constructor	Description
`QConstraintPtr()`	Default constructor yielding a NULL-pointer.
`QConstraintPtr(long cPtr, boolean cMemoryOwn)`
`QConstraintPtr(QConstraint 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
`QConstraint`	`__ref__()`	Dereferencing operator.
`QConstraintCPtr`	`asCPtr()`
`void`	`delete()`
`QConstraint`	`deref()`	The pointer stored in the object.
`boolean`	`equals(QConstraint p)`
`static long`	`getCPtr(QConstraintPtr obj)`
`QConstraint`	`getDeref()`	Member access operator.
`boolean`	`inCollision(Q q)`	True if the work cell is considered to be in collision for the device configuration q.
`boolean`	`isNull()`	checks if the pointer is null
`boolean`	`isShared()`	check if this Ptr has shared ownership or none ownership
`QConstraintPtr`	`make(CollisionDetectorPtr detector, DeviceCPtr device, State state)`	Map a collision detector to a configuration constraint.
`QConstraintPtr`	`make(StateConstraintPtr detector, DeviceCPtr device, State state)`	Map a state constraint to a configuration constraint.
`QConstraintPtr`	`makeBounds(PairQ bounds)`	Constraint for the bounds of the configuration space. The configuration is considered to be in collision if it is outside of the bounds given by bounds.
`QConstraintPtr`	`makeFixed(boolean value)`	A fixed constraint. The fixed constraint always returns value from inCollision().

`QConstraintPtr`	`makeNormalized(QConstraintPtr constraint, PairQ bounds)`	Map a configuration constraint for standard configurations into a configuration constraint for normalized configurations. Configuration values are mapped from the range [0, 1] into the corresponding position in the box bounds.
`QConstraintPtr`	`makeNormalized(QConstraintPtr constraint, Device device)`	Map a configuration constraint for standard configurations into a configuration constraint for normalized configurations. Configuration values are mapped from the range [0, 1] into the corresponding position in the configuration space of device.
`QConstraintPtr`	`makeNormalized(QConstraintPtr constraint, QNormalizer normalizer)`	Map a configuration constraint for standard configurations into a configuration constraint for normalized configurations. Configuration values are mapped from normalized configurations into standard configurations using normalizer.
`void`	`setLog(LogPtr log)`	Set the log to be used for writing debug info
`void`	`update(State state)`	Updates the constraint with a new state The method might not have an effect on all constrainttypes.
