AbstractionLevelAttribute
This is a subclass of TimingRequirementAttribute, which includes Instrument-AbstractionLevel, Method-AbstractionLevel, Object-AbstractionLevel, Task-AbstractionLevel, and TaskGroup-AbstractionLevel.
Relationships      
Parents TimingRequirementAttribute A subclass of RealtimeSystemAttribute which includes ComplexityAttribute, StrictnessAttribute, and AbstractionLevelAttribute.
Children InstrumentAbstractionLevelThe attribute Instrument-AbstractionLevel is the lowest level of abstraction, which can be used to describe a real-time system or subsystem.
 MethodAbstractionLevelThe attribute Method-AbstractionLevel is the next to the lowest level of abstraction that can be used to describe a real-time system or subsystem. This is at the level of describing every callable function (or method in an object-oriented language) implemented in software.
 ObjectAbstractionLevelThe attribute Object-AbstractionLevel is immediately above the attribute Method-AbstractionLevel and can be used to describe a real-time system or subsystem. This is at the level of describing every software object that can be created from a class together with its data structures and methods (which define the interface for manipulating the object).
 TaskAbstractionLevelThe attribute Task-AbstractionLevel is immediately above the attribute Object-AbstractionLevel and can be used to describe a real-time system or subsystem. This is at the level of describing the major tasks that are carried out by the real-time systems and are typically executable as individual processes. The description of a task would consist of listing all the software objects used to perform the task.
 TaskGroupAbstractionLevelThe attribute TaskGroup-AbstractionLevel is immediately above the attribute Task-AbstractionLevel and can be used to describe a real-time system or subsystem This is at the level of describing groups of tasks which are related or connected by the real-time systems and are typically part of a concurrently executing path.
