public interface ValueMap
A valueMap can be specified as either an Array of legal values, or as an
Object where each property maps a stored value to a user-displayable value. See
DataSourceField.valueMap for how to express a ValueMap in
A ValueMap can be entirely static or entirely dynamic, with many options in between. For example, a ValueMap may be:
DataSource.fetchData()where a valueMap is derived dynamically from the returned data (see
DataSource.fetchData()for an example). Such a valueMap may be updated at any time, for example, every time the user changes a related field while editing data.
