Detailed Description

Base abstraction for Actions for DataTrigger, such as ForwardingApplyAction and ApplyActivationAction.

An ApplyAction applies the changes described in the Action on apply(), and reverts them on unapply().

See also: ApplyAction::apply(), ApplyAction::unapply()

Since: Kanzi 3.9.0

Member Typedef Documentation

◆ PropertyValidatorFunctionType

using kanzi::ApplyAction::PropertyValidatorFunctionType = function<bool(const Variant& value)>

protected

Validator function to validate if a change in a property is valid to apply the Action or not.

Constructor & Destructor Documentation

◆ ApplyAction()

kanzi::ApplyAction::ApplyAction	(	Domain *	domain,
		string_view	name
	)

explicitprotected

Constructor.

Parameters

domain	Domain.
name	Name of the constructed ApplyAction.

Member Function Documentation

◆ makeEditorInfo()

static PropertyTypeEditorInfoSharedPtr kanzi::ApplyAction::makeEditorInfo ( )

static

Provides the Kanzi Studio editor metadata for the ApplyAction.

Returns: Shared pointer to the created PropertyTypeEditorInfo instance.

◆ apply()

void kanzi::ApplyAction::apply ( )

Applies an ApplyAction to the node that this action targets.

◆ unapply()

void kanzi::ApplyAction::unapply ( )

Unapplies an ApplyAction by rolling back the changes made on apply(), and restoring the state of the target node to its previous value.

◆ copy()

ApplyActionSharedPtr kanzi::ApplyAction::copy ( ) const

Returns: Shared pointer to the created ApplyAction instance.

◆ getTrigger()

DataTriggerComponent* kanzi::ApplyAction::getTrigger ( ) const

Returns the pointer to a DataTrigger to which an Action is attached.

Returns: The pointer to the DataTrigger.

◆ attach()

void kanzi::ApplyAction::attach ( DataTriggerComponent * trigger )

Attaches an Action to a DataTrigger.

Parameters

trigger Pointer to the DataTrigger to which you want to attach the Action.

◆ detach()

void kanzi::ApplyAction::detach ( )

Detaches the Action from the DataTrigger.

◆ applyWhenTargetIsAlive()

void kanzi::ApplyAction::applyWhenTargetIsAlive	(	NodeSharedPtr	hostNode,
		string_view	targetPath,
		AbstractPropertyType	targetPropertyType,
		PropertyValidatorFunctionType	isPropertyChangeValid
	)

protected

Use this method when Kanzi cannot find the node on which to apply an Action during ApplyAction.

This method observes the path that you pass. When the node in that path becomes available, the method applies the Action. In case the Action is unapplied before the node becomes available, the class stops observing the path that you pass.

Parameters

hostNode	The node to which the modifier binding is added.
targetPath	The path to an unavailable node to which you want to apply an Action.
targetPropertyType	The property type, on the target node, to listen to.
isPropertyChangeValid	Validator function to validate if a change in targetPropertyType property is valid to apply the Action or not.

◆ clone()

virtual ApplyActionSharedPtr kanzi::ApplyAction::clone ( ) const

protectedpure virtual

Overridable function for copying an ApplyAction.

Implementations must call onCopy() on the new instances.

Implemented in kanzi::ApplyActivationAction, and kanzi::ApplyPropertyAction.

◆ applyOverride()

virtual void kanzi::ApplyAction::applyOverride ( )

protectedpure virtual

Overridable method to apply an ApplyAction.

Implemented in kanzi::ApplyActivationAction, and kanzi::ApplyPropertyAction.

◆ unapplyOverride()

virtual void kanzi::ApplyAction::unapplyOverride ( )

protectedpure virtual

Overridable method to unapply an ApplyAction and restore the DataTriggerComponent node to its previous state.

Implemented in kanzi::ApplyActivationAction, and kanzi::ApplyPropertyAction.
