Synopsis

MeasConvert can convert a Measure to the same type of Measure in a different reference frame. The MeasConvert is a templated class, but has typedefs, which are strongly recommended to be used, for the allowed conversions, like MEpoch::Convert.
The basic operation is to create a MeasConvert with either of:

An empty MeasRef argument indicates no conversion will be attempted
. The constructor, and set functions, analyse the 'template' Measure and the output reference frame, and construct a pointer (in practice a list of pointers to bypass the necessity of creating too many conversion functions) to a conversion routine.

An isNOP() function is available to test if the created conversion engine is empty.

Actual conversions are done with the () operator, which produces a new MEpoch (or other appropiate Measure).
Possible arguments are (MVEpoch is used here generic, and indicates the internal format of a Measure; possibly, to make sure distinction between values with and without units possible, even simple Measures will have their own internal class format, e.g. MVDouble. The possible arguments to the () conversion operator are (again Epoch is used for the generic Measure):

Float versions will be produced if necessary.
The conversion analyser expects that all Measure classes have a set of routines to do the actual analysing and conversion. (see MCBase class for how this is done in practice).
If the standard conversion is not sufficient, additional methods can be added at the end of the list with the addMethod() member function (for real pros).

Example

See Measure for an example

Motivation

Conversion of Measures will in general be done on a series of values. Separating the analysis of the calculations necessary for the conversion from the actual conversion could speed up the process.
