slreportgen.finder.DiagramFinder class

Package: slreportgen.finder

Create finder for diagrams

Description

Finds Simulink® diagrams and Stateflow® charts.

The slreportgen.finder.DiagramFinder class is a handle class.

Creation

Description

example

finder = DiagramFinder(container) creates a finder that finds by default all uncommented Simulink block diagrams and Stateflow chart diagrams in the specified container. To constrain the search to include specific types of diagrams, use the properties of this finder.

Note

This finder can operate in either find or iterator mode. In find mode, use its find method to return the results of a search as an array of results. In iterator mode, use its hasNext and next methods to return the results of a search one-by-one. When searching in models that have many model references, use iterator mode. Iterator mode closes a model after compiling and searching it, whereas find mode keeps all the models that it searches open. Having many open models can consume all system memory and slow report generation. Iterator mode is slower than find mode, so use find mode to search models that reference few or no other models.

example

finder = DiagramFinder(Name=Value) sets properties using name-value pairs. You can specify multiple name-value pair arguments in any order.

See Container property.

Properties

expand all

Model container in which to search, specified as one of these values:

  • Handle of a Simulink model, subsystem, or model block

  • Path to a Simulink model, subsystem, or model block

  • Handle of a Stateflow chart block

  • Path to a Stateflow chart block

  • Stateflow chart ID

  • Stateflow chart object

Depth of system diagram search, specified as inf or a positive integer. SearchDepth specifies how many levels deep to search a diagram container for diagrams. To search all levels, use inf.

Choice to search masked subsystems, specified as a logical. If this property is true, the finder searches masked Subsystem blocks in the diagram container. It searches to the specified SearchDepth and includes the diagrams it finds in the search results.

Choice to search referenced models, specified as a logical. If this property is true, the finder searches models referenced in the diagram container. It searches to the specified SearchDepth and includes the diagrams it finds in the search results.

Whether to search referenced subsystems, specified as numeric or logical 1 (true) or 0 (false).

Choice to search Simulink library links, specified as a logical. If both this property and IncludeMaskedSubsystems are true, the finder searches links in the diagram container to both Subsystem and masked Subsystem blocks in Simulink libraries. It searches to the specified SearchDepth and includes the diagrams it finds in the search results. If this property is true, but IncludeMaskedSubsystems is false, the finder searches only links to Subsystem blocks in Simulink libraries.

Choice to search user library links, specified as a logical. If this property is true and the IncludeMaskedSubsystems property is true, the finder searches links in the diagram container to Subsystem and masked Subsystem blocks in user libraries. It searches to the specified SearchDepth and includes the diagrams it finds in the search results. If this property is true, but the IncludeMaskedSubsystems property is false, the finder searches only links to Subsystem blocks in user libraries.

Whether to include commented-out diagrams in the search results, specified as a logical. If false, commented-out diagrams are excluded from the search results.

Variants to search for diagrams, specified as a string or character vector. The default value is Active. Valid values are:

  • All — All variants

  • Active — Only active variants

  • ActivePlusCode — All active variants and code variants

Properties of objects to find, specified as a cell array of name-value pairs. The finder returns only objects that have the specified properties with the specified values.

Example: finder.Properties = {'Gain','5'}

Whether to close models, specified as true or false. If true, the next method of the finder closes the currently open model before moving to the next model to search. Closing models prevents excessive consumption of memory when searching a model that references many models.

Note

The find method of the finder ignores this property and leaves all referenced models open. For this reason, you should not use the find method to search models with many model references.

Examples

Create a report that includes an image of all diagrams in the slrgex_sf_car model. Although the model used in this example does not contain model references, the example uses iterator mode to illustrate its syntax.

import mlreportgen.report.*
import slreportgen.report.*
import slreportgen.finder.*

model_name = 'slrgex_sf_car';
load_system(model_name);
rpt = slreportgen.report.Report('output','pdf');
add(rpt, TitlePage(Title=sprintf('%s Systems',model_name)));

finder = DiagramFinder(model_name); 
while hasNext(finder)
    add(rpt,next(finder));
end    

close(rpt);
close_system(model_name);
rptview(rpt);

Open the slrgex_sf_car model and find all the diagrams in its Engine subsystem. Use either the path to the subsystem or its handle. You can then include the results in your report.

slrgex_sf_car

% Use path 
enginePath = "slrgex_sf_car/Engine";
finder = slreportgen.finder.DiagramFinder(enginePath);
results = find(finder);

% or use handle
engineHandle = get_param("slrgex_sf_car/Engine","Handle");
finder = slreportgen.finder.DiagramFinder(engineHandle);
results_enginehandle = find(finder);

To find elements with specific property values, use an object of the slreportgen.finder.DiagramElementFinder class. Open the f14 model and find all Gain blocks with a value of Zw.

model = 'f14';
load_system(model);
finder = slreportgen.finder.DiagramElementFinder(model)
finder.Properties = {'Gain','Zw'};
results = find(finder);
