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

Constructor Summary

Constructors
Constructor	Description
`TrajectorySequenceQPtr()`	Default constructor yielding a NULL-pointer.
`TrajectorySequenceQPtr(long cPtr, boolean cMemoryOwn)`
`TrajectorySequenceQPtr(TrajectorySequenceQ 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
`TrajectorySequenceQ`	`__ref__()`	Dereferencing operator.
`TrajectorySequenceQCPtr`	`cptr()`
`Q`	`ddx(double t)`
`void`	`delete()`
`TrajectorySequenceQ`	`deref()`	The pointer stored in the object.
`double`	`duration()`
`Q`	`dx(double t)`
`double`	`endTime()`	Returns the endTime of the trajectory. The end time equals startTime() + duration().
`boolean`	`equals(TrajectorySequenceQ p)`
`static long`	`getCPtr(TrajectorySequenceQPtr obj)`
`TrajectorySequenceQ`	`getDeref()`	Member access operator.
`TrajectoryIteratorQPtr`	`getIterator(double dt)`
`VectorQ`	`getPath(double dt)`	Constructs a discrete path based on the trajectory. If uniform = true the path will be divided into the smallest number of uniform steps for which the time stepsize <= dt. If uniform = false the path is divided into steps of duration dt, except the last interval which may be shorter to include the end point.
`VectorQ`	`getPath(double dt, boolean uniform)`	Constructs a discrete path based on the trajectory. If uniform = true the path will be divided into the smallest number of uniform steps for which the time stepsize <= dt. If uniform = false the path is divided into steps of duration dt, except the last interval which may be shorter to include the end point.
`boolean`	`isNull()`	checks if the pointer is null
`boolean`	`isShared()`	check if this Ptr has shared ownership or none ownership
`double`	`startTime()`
`Q`	`x(double t)`
