padv.builtin.query.FindExternalCodeCache Class

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

Query for finding external code cache files in project folder

Description

The padv.builtin.query.FindExternalCodeCache class provides a query that can return the external code cache files (.slxc.bk) 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 artifacts for your tasks to use as inputs. For example, you can use this query to the find external code cache files that you generate using the built-in task padv.builtin.task.GenerateCode. The built-in task padv.builtin.task.GenerateCode generates an external code cache when you specify the task property GenerateExternalCodeCache as true. To unpack the code generation target from the cache files, you can use the utility function padv.util.unpackExternalCodeCache.

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

Creation

Description

query = padv.builtin.query.FindExternalCodeCache() creates a query for finding the external code cache files (.slxc.bk) in your project folder.

query = padv.builtin.query.FindExternalCodeCache(Name = queryName) specifies a new name, queryName, for the query object. Each query in the process model must have a unique name.

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

Input Arguments

queryName — Unique identifier for query

string

Unique identifier for query, specified as a string.

This argument specifies the value for the Name property.

Example: "FindMyExternalCodeCache"

Data Types: string

Parent — Initial query that runs before iteration query

string.empty() (default) | padv.Query | Name of padv.Query object

You cannot use FindExternalCodeCache as an iteration query, so the build system does not use the parent query.

Name — Unique identifier for query

string

Unique identifier for query, specified as a string.

Example: "FindMyExternalCodeCache"

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. 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

Examples

Find and Unpack Cache Files for Task in Process

You can use the FindExternalCodeCache query in your task definition to find and unpack external code cache files. For example, suppose your team generates code in parallel by generating an external code cache, downstream tasks that depend on the generated code need to unpack the generated code target before performing the main task action. If you have a custom task that depends on that generated code, you can find the external code cache files by using the built-in query FindExternalCodeCache and unpack the code generation target by using the utility function padv.util.unpackExternalCodeCache.

Inside your task definition, you can find external code cache files by creating and running a FindExternalCodeCache query object. For example:

% Before main task action, access the generated code
% by finding and unpacking the external code cache
q = padv.builtin.query.FindExternalCodeCache;
artifactsArray = run(q);
    if ~isempty(artifactsArray)
        padv.util.unpackExternalCodeCache(artifactsArray)
    end

% <definition for main task action that uses the generated code>

For more information about parallel code generation and external code caches, see the GenerateExternalCodeCache property for the built-in task padv.builtin.task.GenerateCode. The external code cache allows your team to generate code in parallel while maintaining up-to-date task results.

Test FindExternalCodeCache Query Outside Process Model

Although you typically use a query inside your process model, you can run an instance of the FindExternalCodeCache query outside of your process model to confirm which artifacts the query returns.

Open the parallel code generation example.

processAdvisorParallelExampleStart

Generate code by running a code generation task iteration. For example, run the code generation task on the reference model OuterLoop_Control.

runprocess(Tasks = "padv.builtin.task.GenerateCode", ...
    FilterArtifact = fullfile("02_Models","OuterLoop_Control", ...
    "specification","OuterLoop_Control.slx"));

Find the external code cache file by using the built-in query.

q = padv.builtin.query.FindExternalCodeCache;
artifactsArray = run(q);

Unpack the cache file.

padv.util.unpackExternalCodeCache(artifactsArray);
