MetricBase is a base class for metrics used for Adaptive Bitrate. A metric's value is computed based on QoSInfoHistory. A metric is identified by its type.
The base class handles the caching of the computed value. The subclasses should only implement the actual computation.
All subclasses should have qosInfoHistory as the first parameter in the constructor.
All subclasses must set the _type in the constructor.
