context | RenderingContext | Rendering Context |
boolean
true if object is inside of renderable area
▸ clone(): Node
All subclasses should override copyConstructor or provide custom implementation for this method
clone
▸ connectStyle(style, type, callback): AnimatedNode
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
| Name | Type | Description |
|---|---|---|
style | EventDispatcher | connect style |
type | string | type of event or property |
callback | AttributeCallback<EventDispatcher> | function to be called |
this
▸ Protected copyConstructor(src, deepCopy?): AnimatedNode
Copy constructor function.
Function used as part of the cloning mechanism.
Implementations should copy the given instance state to this instance.
| Name | Type | Description |
|---|---|---|
src | AnimatedNode | Source to copy from |
Optional deepCopy | boolean | deep copy |
this
▸ disconnectStyle(style, type, callback): AnimatedNode
Disconnect style
This convenience method un-subscribes a listener to given style for the specified type.
| Name | Type | Description |
|---|---|---|
style | EventDispatcher | connect style |
type | string | type of event or property |
callback | AttributeCallback<EventDispatcher> | function to be called |
this
▸ dispose(): void
Disposes this node, once disposes a node should not be used anymore.
Clear all listeners, and disconnect styles to avoid memory leaks.
Also aggressively 'cleanup' this node by setting some of its members to null.
void
▸ enableEventPropagation(enable): AnimatedNode
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 {Group} from '@int/geotoolkit/scene/Group';
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();| Name | Type | Description |
|---|---|---|
enable | boolean | enable |
this
▸ execute(delegate): AnimatedNode
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");
