padv.builtin.query.FindRequirementsForModel Class

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

Query for finding requirements for model

Description

The padv.builtin.query.FindRequirementsForModel class provides a query that can return each of the requirements associated with a model. You can automatically include or exclude certain artifacts by using the optional name-value arguments.

You can use this query in your process model to find artifacts for your tasks to iterate over or use as inputs. To find each of the requirements in your project, you can use padv.builtin.query.FindRequirements instead.

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

Creation

Description

query = padv.builtin.query.FindRequirementsForModel() creates a query for finding each of the requirements associated with a model.

query = padv.builtin.query.FindRequirementsForModel(Name=Value) sets certain properties using one or more name-value arguments. For example, padv.builtin.query.FindRequirementsForModel(IncludePath="System") creates a query object to find requirements that include System in the full file path.

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

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: query = padv.builtin.query.FindRequirementsForModel(IncludePath="System")

Parent — Initial query run before iteration query

"padv.builtin.query.FindModels" (default) | padv.Query object | Name of padv.Query object

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

The build system ignores the Parent query when you specify a query as an input query or dependency query for a task.

Parent — Initial query run before iteration query

"padv.builtin.query.FindModels" (default) | padv.Query object | Name of padv.Query object

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

The build system ignores the Parent query when you specify a query as an input query or dependency query for a task.

Example: padv.builtin.query.FindModels

Example: padv.builtin.query.FindModels(IncludePath = "Control")

Name — Unique identifier for query

string

Unique identifier for query, specified as a string.

Example: "FindMyRequirements"

Data Types: string

ShowFileExtension — Show file extensions for returned artifacts

0 (false) | 1 (true)

Show file extensions in the Alias property of returned artifacts, 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 artifacts by address

true or 1 (default) | false or 0

Setting for automatically sorting artifacts 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

Methods

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 that are associated with the artifact iterationArtifact. If you inherit from this built-in query, make sure to use the same method signature inside your custom query: function artifacts = run(obj,iterationArtifact) ... end The query only supports iteration artifacts with these artifact types: "sl_model_file" — Simulink model files "sl_subsystem_file" — Simulink subsystem file "zc_file" — System Composer architecture file For more information on artifact types, see Valid Artifact Types.

Examples

Find and Run Tasks Using Requirements

You can use the FindRequirementsForModel query in your process model to find requirements for your tasks to iterate over (IterationQuery) or use as inputs (addInputQueries).

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

processAdvisorExampleStart

Edit the process model to use the following process model instead.

function processmodel(pm)
    % Defines the project's processmodel

    arguments
        pm padv.ProcessModel
    end

    t1 = pm.addTask("TaskInputsAreReqs",...
        Iterationquery = padv.builtin.query.FindModels(...
        IncludePath = "AHRS_Voter.slx"),...
        InputQueries = padv.builtin.query.FindRequirementsForModel());

    t2 = pm.addTask("TaskIteratesOverModelReqs",...
        IterationQuery = padv.builtin.query.FindRequirementsForModel(...
        Parent =  padv.builtin.query.FindModels(IncludePath = "AHRS_Voter.slx")));

end

This process model adds two custom tasks to the process. The code configures task t1 to run on the model InnerLoop_Control and to use the requirements associated with that model as inputs to the task. The code configures task t2 to run on each requirement associated with the model InnerLoop_Control.

In Process Advisor, view the updated Tasks by clicking Refresh Tasks and switching to the Project view.

Capabilities and Limitations

This table identifies functionality that is supported by the query.

Functionality	Supported?
Input query for task	Yes.
Iteration query for task	Yes.

Note

If you use this query as an input query and specify non-empty values for IncludeLabel, ExcludeLabel, IncludePath, or ExcludePath, your task results can unexpectedly become outdated. If you see this behavior, consider using a different query, like padv.builtin.query.FindArtifacts, instead. For more information and a list of queries that are not impacted by this limitation, see Other Limitations.
