Detailed Description

A prefab template node contains information that is required to create node instances: the metaclass of the node, the (initial) property values of the node, information about the bindings and node components of the node, and the list of of child nodes.

Typically prefab templates nodes are defined in Kanzi Studio and loaded from a kzb file as PrefabTemplate resources. A Prefab template contains a tree of prefab template nodes and can be used to instantiate a tree of nodes.

Note that nodes can be created also directly by using the create function in each Node class. You don't necessarily need to use PrefabTemplate or PrefabTemplateNode instances.

A prefab template node can represent either a normal node with a metaclass, or a placeholder that replaces itself with the root of another prefab template when instantiated. Prefab template nodes and their children should always form a simple tree structure. Creating a cycle with prefab placeholders is not allowed.

Member Function Documentation

◆ create()

static PrefabTemplateNodeSharedPtr kanzi::PrefabTemplateNode::create	(	Domain *	domain,
		const Metaclass *	metaclass,
		string_view	name
	)

static

Creates a prefab template node that can be instantiated to create a node.

Parameters

domain	The domain to use.
metaclass	The metaclass of the created node.
name	The name of the created node.

◆ createPlaceholder()

static PrefabTemplateNodeSharedPtr kanzi::PrefabTemplateNode::createPlaceholder	(	Domain *	domain,
		PrefabTemplateSharedPtr	instantiatedPrefab,
		string_view	name
	)

static

Creates a prefab template node that can be instantiated to create an instance of another prefab template.

Parameters

domain	The domain to use.
instantiatedPrefab	A reference to another prefab that will be instantiated in place of this prefab template node.
name	The name of the placeholder node. Overrides the name of the root node of the referenced prefab template.

◆ instantiate()

NodeSharedPtr kanzi::PrefabTemplateNode::instantiate ( NodeSharedPtr templateRoot )

Creates a tree of nodes by instantiating a prefab template node and its children.

Parameters

templateRoot A Pointer to an existing node instance that will act as the template root for the instantiated node tree. Any ##Template bindings in the prefab resolve to this node. If the templateRoot is set to nullptr, the newly instantiated root node will act as the template root.

Returns: Pointer to the root node of the created node tree.

◆ addBinding()

void kanzi::PrefabTemplateNode::addBinding ( BindingLoadInfo createInfo )

inline

Adds a binding to the prefab template node.

This binding will be added to the node on creation.

Parameters

createInfo Binding to add.

◆ addChild()

void kanzi::PrefabTemplateNode::addChild ( PrefabTemplateNodeSharedPtr child )

inline

Adds a child for the prefab template node.

Parameters

child Child prefab template node.

◆ addProperty()

void kanzi::PrefabTemplateNode::addProperty	(	AbstractPropertyType	propertyType,
		const Variant &	value
	)

inline

Adds a property value to the prefab template node.

Parameters

propertyType	Property type to add.
value	Property value to add.

◆ addResourceDictionaryEntry()

void kanzi::PrefabTemplateNode::addResourceDictionaryEntry	(	const ResourceID &	resourceID,
		string_view	resourceURL
	)

Adds an entry to the resource dictionary of the prefab template node.

If the prefab template node does not have a resource dictionary, this function creates the dictionary first.

Parameters

resourceID	The key of the dictionary entry.
resourceURL	The value of the dictionary entry.

◆ getMetaclass()

const Metaclass* kanzi::PrefabTemplateNode::getMetaclass ( ) const

inline

Gets the metaclass of the prefab template node.

Returns: The metaclass of the prefab template node.

◆ cleanupInstances()

void kanzi::PrefabTemplateNode::cleanupInstances ( )

Cleans up expired elements from instances.

Only used when running inside Kanzi preview. Outside the Kanzi preview does not do anything.

◆ referencedPrefab

PrefabTemplateSharedPtr kanzi::PrefabTemplateNode::referencedPrefab

Reference to another prefab template if the template node is a prefab placeholder.

If the prefab template node is not a placeholder, it needs to have a typeIdentifier.
