DOmeasures.h

The class makes the connection between the Measures module and the Glish distributed object system. It provides a series of Glish callable methods. See Aips++ Note 197 for details.
The parameter interface between Glish and the distributed objects knows about Measures, and can convert them. Operations supported are all the conversion and testing related ones; both in CLI and a GUI related methods.

The class name is measures, the file name DOmeasures, with the actual distributed object in measures.cc, measures.g

Example

For an example of the class use, see the measures.g application.

Motivation

To provide a direct user interface between the user and Measures related calculations and conversions; including coordinate and time conversions.

To Do

Change to/fromRecord conversions after new Parameter interface
