Modifier and Type	Method	Description
`double`	`approximate(T v)`
`double`	`approxLength(int samples)`
`T`	`derivativeAt(T out, double t)`
`double`	`locate(T v)`

- Method Detail
  - derivativeAt
```
T derivativeAt(T out,
               double t)
```
  - valueAt
```
T valueAt(T out,
          double t)
```
    Returns:
    
    The value of the path at t where 0<=t<=1
  - approximate
```
double approximate(T v)
```
    Returns:
    
    The approximated value (between 0 and 1) on the path which is closest to the specified value. Note that the implementation of this method might be optimized for speed against precision, see locate(Object) for a more precise (but more intensive) method.
  - locate
```
double locate(T v)
```
    Returns:
    
    The precise location (between 0 and 1) on the path which is closest to the specified value. Note that the implementation of this method might be CPU intensive, see approximate(Object) for a faster (but less precise) method.
  - approxLength
```
double approxLength(int samples)
```
    Parameters:
    
    samples - The amount of divisions used to approximate length. Higher values will produce more precise results, but will be more CPU intensive.
    
    Returns:
    
    An approximated length of the spline through sampling the curve and accumulating the euclidean distances between the sample points.
