VersionResults

Results of upgrade operations

Description

A VersionResults object contains the results of each operation when upgrading the personal settings of a toolbox.

Creation

Create a ReleaseCompatibilityResults object for a specific toolbox version number by using the matlab.settings.loadSettingsCompatibilityResults function. Then, access the Results property to get the VersionResults object.

For example, this code gets the VersionResults object for version 2 of the toolbox mytoolbox.

myCompatibilityResults = matlab.settings.loadSettingsCompatibilityResults('mytoolbox','Version2');
myCompatibilityResults.Results
ans = 
  VersionResults with properties:
      VersionLabel: "Version2"
    VersionChanges: [1×2 matlab.settings.OperationResult]

Properties

Toolbox version of results, specified as a string scalar.

Example: "Version2"

Status for each upgrade operation, specified as an array of operation result objects.

Create functions to create and then upgrade a toolbox factory tree and then test that the upgrade completes successfully.

The function createMyToolboxFactoryTree creates the factory settings tree for the toolbox mytoolbox.

function myToolboxFactoryTree = createMyToolboxFactoryTree()
    myToolboxFactoryTree = matlab.settings.FactoryGroup.createToolboxGroup('mytoolbox', ...
        'Hidden',false);

    toolboxFontGroup = addGroup(myToolboxFactoryTree,'font','Hidden',false)
    addSetting(toolboxFontGroup,'MyFontSize','FactoryValue',11,'Hidden',false, ...
        'ValidationFcn',@matlab.settings.mustBeNumericScalar)    
    addSetting(toolboxFontGroup,'MyFontColor','FactoryValue','Black', ...
        'Hidden',false,'ValidationFcn',@matlab.settings.mustBeStringScalar);
end

Create the function createMyToolboxSettingsFileUpgraders with an empty matlab.settings.SettingsFileUpgrader object.

function upgraders = createMyToolboxSettingsFileUpgraders()
    upgraders = matlab.settings.SettingsFileUpgrader.empty;
end

Create the settingsInfo.json file for the toolbox. Specify mytoolbox as the root settings group name, createMyToolboxFactoryTree as the settings tree creation function, and createMyToolboxSettingsFileUpgraders as the settings tree upgrade function. Place settingsInfo.json in the toolbox resources folder.

{
"ToolboxGroupName" : "mytoolbox",
"Hidden" : false,
"CreateTreeFcn" : "createMyToolboxFactoryTree",
"CreateUpgradersFcn" : "createMyToolboxSettingsFileUpgraders"
}

Add the folder that contains the settings tree creation function and the toolbox resources folder to the MATLAB® path. Then, load the factory settings tree for mytoolbox.

matlab.settings.reloadFactoryFile('mytoolbox');

Use the settings function to access the root of the settings tree and set the personal value for the MyFontSize setting.

s = settings;
s.mytoolbox.font.MyFontSize.PersonalValue = 15;

Change the settings names in createMyToolboxFactoryTree from MyFontSize and MyFontColor to FontSize and FontColor.

function myToolboxFactoryTree = createMyToolboxFactoryTree()
    myToolboxFactoryTree = matlab.settings.FactoryGroup.createToolboxGroup('mytoolbox', ...
        'Hidden',false);

    toolboxFontGroup = addGroup(myToolboxFactoryTree,'font','Hidden',false)
    addSetting(toolboxFontGroup,'FontSize','FactoryValue',11,'Hidden',false, ...
        'ValidationFcn',@matlab.settings.mustBeNumericScalar)    
    addSetting(toolboxFontGroup,'FontColor','FactoryValue','Black', ...
        'Hidden',false,'ValidationFcn',@matlab.settings.mustBeStringScalar);
end

Record the rename of the two settings in the createMyToolboxSettingsFileUpgraders function as changes to the settings tree for version 2 of mytoolbox.

function upgraders = createMyToolboxSettingsFileUpgraders()
    upgraders = matlab.settings.SettingsFileUpgrader('Version2'); 
    move(upgraders,'mytoolbox.font.MyFontSize','mytoolbox.font.FontSize'); 
    move(upgraders,'mytoolbox.font.MyFontColor','mytoolbox.font.FontColor');
end

Reload the factory settings tree for mytoolbox.

matlab.settings.reloadFactoryFile('mytoolbox');

Use the settings function to access the root of the settings tree and verify that the personal value for the FontSize setting was correctly moved from the MyFontSize setting.

s = settings;
s.mytoolbox.font.FontSize
ans = 
  Setting 'mytoolbox.font.FontSize' with properties:
       ActiveValue: 15
    TemporaryValue: <no value>
     PersonalValue: 15
      FactoryValue: 11

Get the results of each upgrade operation for version 2 of mytoolbox.

compatibilityResults = matlab.settings.loadSettingsCompatibilityResults('mytoolbox','Version2');
compatibilityResults.Results
ans = 
  VersionResults with properties:
      VersionLabel: "Version2"
    VersionChanges: [1×2 matlab.settings.OperationResult]
