padv.builtin.query.FindRequirements Class

Namespace: padv.builtin.query
Superclasses: padv.Query, padv.builtin.query.FindArtifacts

Query for finding requirements

Description

This class requires CI/CD Automation for Simulink Check.

The padv.builtin.query.FindRequirements class provides a query that can return the requirements files in your project folder. You can automatically include or exclude certain files by using the optional name-value arguments.

You can use this query in your process model to find requirements files for your tasks to iterate over or use as inputs.

The padv.builtin.query.FindRequirements class is a handle class.

Creation

Description

query = padv.builtin.query.FindRequirements() creates a query for finding each of the requirements files (.slreqx) in your project folder.

example

query = padv.builtin.query.FindRequirements(Name=Value) sets certain properties using one or more name-value arguments. For example, padv.builtin.query.FindRequirements(IncludePathRegex = "HighLevel.*\.slreqx") creates a query that can find SLREQX files where the path contains HighLevel.

The padv.builtin.query.FindRequirements class also has other properties, but you cannot set those properties during query creation.

`Parent` — Initial query that runs before iteration query
`padv.Query` | `Name` of `padv.Query` object

Initial query that runs before iteration query, specified as either a padv.Query object or the Name of a padv.Query object. When you specify an iteration query for a task, the parent query is the initial query that the build system runs before running the specified iteration query.

For information on how to improve Process Advisor load times by sharing query instances across your process model, see Best Practices for Process Model Authoring.

Example: sharedQuery

Example: "FindMyInitialArtifacts"

`ShowFileExtension` — Show file extensions for returned requirements
`0` (`false`) | `1` (`true`)

Show file extensions in the Alias property of returned requirements, specified as a numeric or logical 1 (true) or 0 (false). The Alias property controls the display name for the artifact in the Tasks column in Process Advisor.

By default, queries strip file extensions from the Alias property of each task iteration artifact. To show file extensions for all artifacts in the Tasks column, select the project setting Show file extensions. To keep file extensions in the results for a specific query, specify the query property ShowFileExtension as true.

Example: true

Data Types: logical

`SortArtifacts` — Setting for automatically sorting requirements by address
`true` or `1` (default) | `false` or `0`

Setting for automatically sorting requirements by address, specified as a numeric or logical 1 (true) or 0 (false). When a query returns artifacts, the artifacts should be in a consistent order. By default, the build system sorts artifacts by the artifact address.

Alternatively, you can sort artifacts in a different order by overriding the internal sortArtifacts method in a subclass that defines a custom sort behavior. For an example, see Sort Artifacts in Specific Order.

The build system automatically calls the sortArtifacts method when using the process model. The sortArtifacts method expects two input arguments: a padv.Query object and a list of padv.Artifact objects returned by the run method. The sortArtifacts method should return a list of sorted padv.Artifact objects.

Example: SortArtifacts = false

Data Types: logical

`FunctionHandle` — Handle to function that function-based query runs
`function_handle`

Handle to the function that a function-based query runs, specified as a function_handle.

If you define your query functionality inside a function and you or the build system call run on the query, the query runs the function specified by the function_handle.

The built-in queries are defined inside classes and do not use the FunctionHandle.

Example: FunctionHandle = @FunctionForQuery

Data Types: function_handle

Specialized Public Methods

This class overrides the following inherited methods.

run

Run query to find the artifacts that meet the criteria specified by the query.

The query returns a padv.Artifact object or an array of padv.Artifact objects that represent those artifacts.

Note

You do not need to manually invoke this method inside your process model. The build system automatically invokes the run method to find artifacts.

The run method inside this built-in query runs on a query object obj and returns artifacts artifacts. If you inherit from this built-in query, make sure to use the same method signature inside your custom query:

function artifacts = run(obj,~)
    ...
end

Find Requirements for Task in Process

You can use the FindRequirements query in your task definition to find requirements files that your tasks can iterate over (IterationQuery) or use as inputs (InputQueries). For example, suppose that you want to add a custom task, MyCustomTask, that runs for each requirement in the project.

Open a project. For this example, you can open the Process Advisor example project.

processAdvisorExampleStart

By default, a new task runs one time for the project.

In the process model, you can add a new custom task and have the task iterate over each requirement in the project by specifying the task IterationQuery as padv.builtin.query.FindRequirements.

    taskObj = addTask(pm, "MyCustomTask",...
        IterationQuery = padv.builtin.query.FindRequirements,...
        InputQueries = padv.builtin.query.GetIterationArtifact);

This code allows the task to use the artifacts returned by IterationQuery as inputs to the task by specifying InputQueries as padv.builtin.query.GetIterationArtifact.

For the Process Advisor example project, when you save the process model and refresh Process Advisor, the custom task MyCustomTask has task iterations for the requirement sets HighLevelReqs and SystemReqs.

Capabilities and Limitations

This table identifies functionality that is supported by the query.

Functionality	Supported?
Input query for task	Only when the query property `InProject` is `false`.
Iteration query for task	Yes.
