QEDModel

public struct QEDModel

QEDModel provides a set of helper methods to aid on persisting a data model ( represented as an array of QEDReport instances and its associated QEDFile instances).

Usage of QEDModel is optional and is meant just as an aid to speed up your data source implementation.
