Examples of simtools.data.DataSourceCollection

simtools.data.DataSourceCollection
A data source collection gathers data sources with strong interdependancy For example, all the data source values may be read from the same file. This strong inter-dependancy is highlighted by: - The delegation of CollectiveDataSource methods here - The same indexing system for all CollectiveDataSource - A common update mechanism. This is an abstract class. Default implementation handles indexing and update mechanism, but subclasses are responsible for handling values together with setting the index corresponding to those values. Two sets of methods are provided: one uses CollectiveDataSource parameters and the other uses integer = position in the vector of the corresponding CollectiveDataSource. They are of course equivalent and the first calls the second. Thus, subclasses should only implement methods with the vector-like API, not the ones with the CollectiveDataSource parameters.
