m abstract method

double m(
  1. int index
)

The m coordinate of the position at the given index.

Returns zero if m is not available for a valid index. You can also use optM that returns m coordinate as a nullable value.

m represents a measurement or a value on a linear referencing system (like time).

The index must be a valid index in this series; 0 <= index < length.

Implementation

double m(int index);
