Synopsis

The conversion of measures like MDirection, MPosition etc have many conversion routines in common. This class combines all of these conversions, including data caches for re-use.

The class is always created by the default constructor. For each operation (like e.g. Precession application), it has three function:

Example

See MCDirection source for how to use the class.

Motivation

To re-use code for a specific measure conversion, and to ease the caching administration for each individual conversion.
