Usage Record
This is the very basic interface to respect for every Usage Record. It mainly define the generic access methods. In particular:
- Getter and Setter for basic fields;
- Generic Key-Value method both to set and retrieve a single value (key:String, value:Comparable<? extends Serializable>);
- Generic Map<String, Comparable<? extends Serializable>> to set all property at once.
Single Usage Record
Used to identify if an UsageRecord is referred to a single operation to account.
Aggregated Usage Record
Used to identify if an UsageRecord is referred to the aggregation of one (degenerate case) or more UsageRecords becoming from different accounting operations.
This interface define additional methods which allow to retry information regarding
- how many SingleUsageRecords were aggregated
- the time interval related to the aggregated SingleUsageRecords
