Detailed Description

NodeComponent is the base class for all node components.

Node component is an isolated piece of logic which can be attached to any node in order to add additional functionality to it. Examples of node component could be Trigger which performs specific actions when certain conditions are met or AnimationPlayer which animates specific properties of the node it is attached to and its child nodes.

Node component can only be attached to a single node at a time. After node component is detached from one node, it can be attached to any other node.

Node component starts to perform its logic after it is attached to a certain node. After node component is detached from its node it becomes inactive and stops to perform its logic.

Called by KanziObject.connectObject(long) when connecting to a native node component.

Parameters

domain	UI Domain where this node belongs.
handle	Native object that is backing this node component.
metaclass	Metaclass data for this node component.

Member Function Documentation

static <Derived extends NodeComponent> ObjectRef<Derived> createDerived	(	Domain	domain,
		String	name,

domain	UI Domain where this node component belongs.
name	Name of the node component
metaclass	Metaclass data of the node component.

Returns: An ObjectRef that holds the created instance.

String getName ( )

Gets the value of NameProperty.

Returns: Current value.

Node getNode ( )

Returns the node the node component is attached to or null if node component is not attached to a node.

Returns: Node the node component is attached to.

NodeComponentState getState ( )

Gets the state of node component indicating if component is attached to a node, detached from any node or in process of attaching/detaching.

Returns: State of node component.

boolean isAttached ( )

Indicates whether node component is attached to a node.

Returns: true if node component is attached, false otherwise.

boolean isAttaching ( )

Indicates whether node component is in the process of attaching to a node.

Returns: true if node component is in the process of attaching, false otherwise.

boolean isAttachingOrAttached ( )

Indicates whether node component is in the process of attaching to a node or already attached.

Returns: true if node component is in the process of attaching or already attached, false otherwise.
