import {Events as SceneEvents} from '@int/geotoolkit/scene/Node';
const parentGroup = new Group()
.setName('ParentGroup')
.enableEventPropagation(true);
const childGroup = new Group()
.setName('ChildGroup');

parentGroup.addChild(childGroup);

▸ execute(delegate): HVBaseScroll

Executes delegate and return the result. It allows us to keep all initialization calls in one place,
and we do not need to scroll up or down in IDE to find how and where it was initialized.

Example

// All setters (.setName() for example) returns reference to the this.
// In order to modify inner object like LineStyle or Pattern, to get this object (property) we should call getter to get object reference.
// Then modify it as shown below in Option 1 or you can use execute methods shown in Option 2.
import {Group} from '@int/geotoolkit/scene/Group';
import {Rect} from '@int/geotoolkit/util/Rect';
// Option 1
const group = new Group()
.setName('MyGroup')
.setBounds(new Rect(0, 0, 42, 16))
.enableClipping(true)
.setTag({'type': 'sometype'});

group.getLineStyle().setPattern('pattern');
return group;

// Options 2 ( using execute method )
return group
.execute(function () {
this.getLineStyle()
.setPattern("pattern");
});
