Detailed Description

NodeComponentTemplate is the base class for all node component templates.

Node component template contains data and logic for instantiating node components of specific type.

Member Typedef Documentation

◆ PropertyEntry

typedef pair<AbstractPropertyType, Variant> kanzi::NodeComponentTemplate::PropertyEntry

Type for property value.

◆ PropertyContainer

typedef vector<PropertyEntry> kanzi::NodeComponentTemplate::PropertyContainer

Container type for property values.

◆ ConstPropertyIterator

typedef PropertyContainer::const_iterator kanzi::NodeComponentTemplate::ConstPropertyIterator

Iterator type for container of property values.

Constructor & Destructor Documentation

◆ ~NodeComponentTemplate()

kanzi::NodeComponentTemplate::~NodeComponentTemplate ( )

override

Destructor.

◆ NodeComponentTemplate()

kanzi::NodeComponentTemplate::NodeComponentTemplate	(	Domain *	domain,
		string_view	name,
		const Metaclass *	nodeComponentMetaclass )

explicitprotected

Constructor.

Parameters

domain	Domain.
name	Name to use for instantiated node components.
nodeComponentMetaclass	Metaclass from which node component is created.

Member Function Documentation

◆ create()

static NodeComponentTemplateSharedPtr kanzi::NodeComponentTemplate::create	(	Domain *	domain,
		string_view	name,
		const Metaclass *	metaclass )

static

Creates instance of node component template.

Parameters

domain	Domain.
name	Name to assign to every instanced node component.
metaclass	Metaclass to create node components from.

Returns: Node component template.

◆ instantiate()

NodeComponentSharedPtr kanzi::NodeComponentTemplate::instantiate ( )

Instantiates node component from the node component template.

Returns: Instanced node component.

◆ load()

virtual void kanzi::NodeComponentTemplate::load	(	KzbFile &	kzbFile,
		KzbMemoryParser &	parser )

virtual

Loads node component template data from a kzb file.

Subclasses of NodeComponentTemplate can override this function to load type-specific data. In this case overridden function should call load() of base class before loading type-specific data.

Parameters

kzbFile	The kzb file from which to load the node component template.
parser	Parser to parse node component template data.

Reimplemented in kanzi::DataTriggerTemplate, and kanzi::TriggerTemplate.

◆ addPropertyValue()

void kanzi::NodeComponentTemplate::addPropertyValue	(	AbstractPropertyType	propertyType,
		Variant	value )

inline

Adds a property to set when instantiating the template.

Parameters

propertyType	Property type.
value	Property value.

◆ beginProperties()

ConstPropertyIterator kanzi::NodeComponentTemplate::beginProperties ( ) const

inline

Gets iterator to the beginning of properties container of the template.

Returns: Const iterator to the beginning of properties container.

◆ endProperties()

ConstPropertyIterator kanzi::NodeComponentTemplate::endProperties ( ) const

inline

Gets iterator to the end of properties container of the template.

Returns: Const iterator to the end of properties container.

◆ onInstantiate()

virtual void kanzi::NodeComponentTemplate::onInstantiate ( NodeComponent & nodeComponent )

protectedvirtual

Initializes instantiated node component.

Subclasses of NodeComponentTemplate can override this function to implemented additional initialization logic for node components of specific type. Overriden function should call onInstantiate() of base class before performing custom initialization logic.

Parameters

nodeComponent Node component to copy data to.

Reimplemented in kanzi::DataTriggerTemplate, and kanzi::TriggerTemplate.

◆ copyProperties()

void kanzi::NodeComponentTemplate::copyProperties ( NodeComponent & component ) const

protected

Copies properties from the node component template to specified node component.

Parameters

component Node component to copy properties to.
