TimingRequirementAttribute
A subclass of
RealtimeSystemAttribute
which includes
ComplexityAttribute
,
StrictnessAttribute
, and
AbstractionLevelAttribute
.
Children
InstrumentAbstractionLevel
The attribute
Instrument-AbstractionLevel
is the lowest level of abstraction, which can be used to describe a real-time system or subsystem.
MethodAbstractionLevel
The 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.
ObjectAbstractionLevel
The 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).
TaskAbstractionLevel
The 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.
TaskGroupAbstractionLevel
The 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.
