onData<X> abstract method
Transforms a given input data.
If null is returned, this object might not have sufficient data to
apply the transformation. For example, if this object's transformation
requires two elements as input (say f(x, y)), the first call to this
function should return null and the second call should return the result
of the operation between the arguments provided in the first (x) and the
second (y) calls.
Implementation
Point3<X, double>? onData<X>(Point3<X, double> data);
