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().

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
domainDomain.
nameName 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
triggerPointer 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
hostNodeThe node to which the modifier binding is added.
targetPathThe path to an unavailable node to which you want to apply an Action.
targetPropertyTypeThe property type, on the target node, to listen to.
isPropertyChangeValidValidator 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.
