decreaseExecutionOrder
Change function execution order to earlier
Description
decreaseExecutionOrder(
decreases
execution order of the specified function functionObj
)functionObj
by 1. If the
function is at the minimum execution order, the decreaseExecutionOrder
method will fail with a warning.
Examples
Change Execution Order of Software Functions
This example shows the software architecture of a throttle position control system and how to schedule the execution order of the root level functions.
model = systemcomposer.openModel("ThrottleControlComposition");
Simulate the model to populate it with functions.
sim("ThrottleControlComposition");
View the function names ordered by execution order.
functions = {model.Architecture.Functions.Name}'
functions = 6x1 cell
{'Actuator_output_5ms' }
{'Controller_run_5ms' }
{'TPS_Primary_read_5ms' }
{'TPS_Secondary_read_5ms'}
{'TP_Monitor_D1' }
{'APP_Sensor_read_10ms' }
Decrease the execution order of the third function.
decreaseExecutionOrder(model.Architecture.Functions(3))
View the function names ordered by execution order.
functions = {model.Architecture.Functions.Name}'
functions = 6x1 cell
{'Actuator_output_5ms' }
{'TPS_Primary_read_5ms' }
{'Controller_run_5ms' }
{'TPS_Secondary_read_5ms'}
{'TP_Monitor_D1' }
{'APP_Sensor_read_10ms' }
The third function is now moved up in execution order, executing earlier.
Increase the execution order of the second function.
increaseExecutionOrder(model.Architecture.Functions(2))
View the function names ordered by execution order.
functions = {model.Architecture.Functions.Name}'
functions = 6x1 cell
{'Actuator_output_5ms' }
{'Controller_run_5ms' }
{'TPS_Primary_read_5ms' }
{'TPS_Secondary_read_5ms'}
{'TP_Monitor_D1' }
{'APP_Sensor_read_10ms' }
The second function is now moved down in execution order, executing later.
Input Arguments
functionObj
— Function
function object
Function, specified as a systemcomposer.arch.Function
object.

Definitions
Term | Definition | Application | More Information |
---|---|---|---|
software architecture | A software architecture is a specialization of an architecture for software-based systems, including the description of software compositions, component functions, and their scheduling. | Use software architectures in System Composer™ to author software architecture models composed of software components, ports, and interfaces. Design your software architecture model, define the execution order of your component functions, simulate your design in the architecture level, and generate code. | |
software component | A software component is a specialization of a component for software entities, including its functions (entry points) and interfaces. | Implement a Simulink® export-function, rate-based, or JMAAB model as a software component, simulate the software architecture model, and generate code. | |
software composition | A software composition is a diagram of software components and connectors that represents a composite software entity, such as a module or application. | Encapsulate functionality by aggregating or nesting multiple software components or compositions. | Modeling the Software Architecture of a Throttle Position Control System |
software function | A software function is an entry point that can be defined in a software component. | You can apply stereotypes to software functions, edit sample times, and specify the function period using the Functions Editor. | Author and Extend Functions for Software Architectures |
class diagram | A class diagram is a graphical representation of a static structural model that displays unique architecture types of the software components optionally with software methods and properties. | Class diagrams capture one instance of each referenced model and show relationships between them. Any component diagram view can be optionally represented as a class diagram for a software architecture model. | Class Diagram View of Software Architectures |
