Examples

Remove Rules from Filter Objects

This example shows how to remove a rule from a coverage filter programmatically.

Open the model and specify coverage settings.

modelName = 'slcoverage_lct_bus';
open_system(modelName);
set_param(modelName,'CovMetricStructuralLevel','MCDC',...
                    'RecordCoverage','on');

Create two BlockSelector objects, blockSel1 and blockSel2.

blockSel1 = slcoverage.BlockSelector(...
            slcoverage.BlockSelectorType.BlockType,'RelationalOperator');
blockSel2 = slcoverage.BlockSelector(...
            slcoverage.BlockSelectorType.BlockInstance,...
            'slcoverage_lct_bus/slCounter/And');

Create a filter object, create two rule objects, and add each rule to the filter object.

filt = slcoverage.Filter;
rule1 = slcoverage.FilterRule(blockSel1,'Tested elsewhere',...
                              slcoverage.FilterMode.Exclude);
rule2 = slcoverage.FilterRule(blockSel2,'Value is never greater than 0');
filt.addRule(rule1);
filt.addRule(rule2);

Review the rules. Look the first rule in the array.

filtRules = filt.rules
filtRules(1)

filtRules = 

  1×2 FilterRule array with properties:

    Selector
    Mode
    Rationale


ans = 

  FilterRule with properties:

     Selector: [1×1 slcoverage.BlockSelector]
         Mode: Exclude
    Rationale: 'Tested elsewhere'

Remove the first rule that you added. Then review the rules to see that the first rule that you added is removed.

filt.removeRule(rule1);
filtRules = filt.rules

filtRules = 

  FilterRule with properties:

     Selector: [1×1 slcoverage.BlockSelector]
         Mode: Justify
    Rationale: 'Value is never greater than 0'
