Deprecated

since 4.0, use Node.on instead

▸ Protected applyOpacity(context): LogAbstractVisual

This method is called to apply opacity if it is specified on the rendering context. The default implementation sets global alpha on the rendering context

LogAbstractVisual

this

▸ clone(): Node

All subclasses should override copyConstructor or provide custom implementation for this method

Node

clone

AbstractNode.clone

▸ connectStyle(style, type, callback): LogAbstractVisual

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

LogAbstractVisual

this

AbstractNode.connectStyle

▸ Protected copyConstructor(src, deepCopy): LogAbstractVisual

Copy constructor function.
Function used as part of the cloning mechanism.
Implementations should copy the given instance state to this instance.

LogAbstractVisual

this

AbstractNode.copyConstructor

▸ disconnectStyle(style, type, callback): LogAbstractVisual

Disconnect style
This convenience method un-subscribes a listener to given style for the specified type.

LogAbstractVisual

this

AbstractNode.disconnectStyle

▸ 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

AbstractNode.dispose

▸ enableEventPropagation(enable): LogAbstractVisual

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();

LogAbstractVisual

this

AbstractNode.enableEventPropagation

▸ execute(delegate): LogAbstractVisual

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");
});
