Class BaseChangesStream

Example

    const model = this.pluginSystem.findInterface(Editor.Model.IModel) as Editor.Model.IModel;
    const scene = model.project.scene;

    // project.history is a BaseChangesStream — use executeAsGroup()
    // to batch multiple mutations into a single undo/redo entry
    const history = model.project.history as Editor.Model.BaseChangesStream;

    const obj1 = scene.createSceneObject('ObjectA');
    const obj2 = scene.createSceneObject('ObjectB');

    // Group renames into one undo step
    history.executeAsGroup('Rename objects', () => {
      obj1.name = 'RenamedA';
      obj2.name = 'RenamedB';
    });
    console.log(`After grouped rename: "${obj1.name}", "${obj2.name}"`);
    // Ctrl+Z will undo both renames at once
