▸ connectStyle(style, type, callback): GeoRSS

Connects style.

This convenience method subscribes a listener to given style for the specified type.
And automatically un-subscribes listener if node is disposed to prevent memory leaks

▸ enableEventPropagation(enable): GeoRSS

Enable event propagation from the node hierarchy from bottom to top

This option is similar to DOM Event bubbling, which allows to get any event from child node. By default it is disabled for better performance.

Example

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);
parentGroup.on(SceneEvents.Invalidate, (eventName, sender, args) => {
// Got notifications from all children of parent group
});
childGroup.invalidate();

this

Vector.enableEventPropagation

▸ execute(delegate): GeoRSS

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");
});
