About Script Editor

Script Editor lets you create scripts, run them within-app to perform whatever tasks you want such as count blocks in a project, list up models by specific conditions…etc.

Show TaggedValues

In order to use TaggedValues, you need to import Profiles.

function printTaggedValueInfo(model) {
    if (model == null) {
        return
    }
    var taggedValues = model.getTaggedValues();
    for each(var taggedValue in taggedValues) {
        print(taggedValue.getKey() + ":" + taggedValue.getValue())

Show TaggedValues of models selected in the diagram

function printSelectedPresentationsTaggedValueInfo() {
    var viewManager = astah.getViewManager()
    var diagramViewManager = viewManager.getDiagramViewManager()
    var selectedPresentations = diagramViewManager.getSelectedPresentations()
    for each(var selectedPresentation in selectedPresentations) {
        printTaggedValueInfo(selectedPresentation.getModel())
    }
}

※ Show TaggedValue script is also required.

Show TaggedValues models selected in the tree

function printSelectedEntitiesTaggedValueInfo() {
    var viewManager = astah.getViewManager()
    var projectViewManager = viewManager.getProjectViewManager()
    var selectedEntities = projectViewManager.getSelectedEntities()
    for each(var selectedEntity in selectedEntities) {
        printTaggedValueInfo(selectedEntity)
    }
}

※ Show TaggedValue script is also required.

List up models with a specific stereotype

var IElement = Java.type('com.change_vision.jude.api.inf.model.IElement');
var Arrays = Java.type('java.util.Arrays');
 
// Search by stereotype
var stereotype = "stereotype";
 
for each(var element in astah.findElements(IElement.class)) {

var infNamespace = 'com.change_vision.jude.api.inf'

var TransactionManager = Java.type(infNamespace + '.editor.TransactionManager');
var Key = Java.type(infNamespace + '.presentation.PresentationPropertyConstants.Key');
