io.neba.core.resourcemodels.metadata.ResourceModelStatistics

public class ResourceModelStatistics
extends Object

Represents statistical data regarding the usage of a ResourceModel. This implementation is intentionally not thread-safe, i.e. the calculations will loose accuracy in case the statics are modified concurrently. This is intended: We can give up some precision in favor of a massive performance gain, as this model is accessed hundreds of times per request, e.g. during page rendering.
However, it is expected that the statistics still provide an accurate picture and gain precision as time passes and data accumulates.
