Detailed Description

Base class for notifications on binding lookup.

Implementing classes have virtual functions to react to either object globally becoming available, or locally potentially changing availability.

Since

Kanzi 3.7.0

Constructor & Destructor Documentation

BindingLookupNotificationBase()

kanzi::BindingLookupNotificationBase::BindingLookupNotificationBase ( )

inlineexplicitprotected

Constructor.

~BindingLookupNotificationBase()

kanzi::BindingLookupNotificationBase::~BindingLookupNotificationBase ( )

inline

Destructor.

Member Function Documentation

isGlobalNotificationInstalled()

bool kanzi::BindingLookupNotificationBase::isGlobalNotificationInstalled ( ) const

inline

Tells if this a global notification has been registered.

Returns

True if global notification registered, false otherwise.

isLocalNotificationInstalled()

bool kanzi::BindingLookupNotificationBase::isLocalNotificationInstalled ( ) const

inline

Tells if this a local notification has been registered.

Returns

True if local notification registered, false otherwise.

clearLocalNotificationFlag()

void kanzi::BindingLookupNotificationBase::clearLocalNotificationFlag ( )

inline

Clears local notification flag.

Should be done if the object local notification was installed for is lost.

registerGlobalNotification()

void kanzi::BindingLookupNotificationBase::registerGlobalNotification	(	BindingLookupContext &	lookupContext,
		string_view	path
	)

Installs a global notification listener.

Parameters

lookupContext	Lookup context to use.
path	Path associated with lookup.

unregisterGlobalNotification()

void kanzi::BindingLookupNotificationBase::unregisterGlobalNotification	(	BindingLookupContext &	lookupContext,
		string_view	path
	)

Uninstalls a global notification listener.

Parameters

lookupContext	Lookup context to use.
path	Path associated with lookup.

registerLocalNotification() [1/2]

void kanzi::BindingLookupNotificationBase::registerLocalNotification	(	BindingLookupContext &	lookupContext,
		PropertyObject *	object,
		string_view	path
	)

Installs a local notification listener.

Object parameter may only be nullptr if path points to a local resource.

Parameters

lookupContext	Lookup context to use.
object	Object to listen on.
path	Path associated with lookup.

registerLocalNotification() [2/2]

void kanzi::BindingLookupNotificationBase::registerLocalNotification ( BindingLookupContext &  lookupContext, PropertyObject &  object, string_view  path  )

inline

Installs a local notification listener.

Parameters

lookupContext	Lookup context to use.
object	Object to listen on.
path	Path associated with lookup.

unregisterLocalNotification() [1/2]

void kanzi::BindingLookupNotificationBase::unregisterLocalNotification	(	BindingLookupContext &	lookupContext,
		PropertyObject *	object,
		string_view	path
	)

Removes a local notification listener.

Object parameter may only be nullptr if path points to a local resource.

Parameters

lookupContext	Lookup context to use.
object	Object to listen on.
path	Path associated with lookup.

unregisterLocalNotification() [2/2]

void kanzi::BindingLookupNotificationBase::unregisterLocalNotification ( BindingLookupContext &  lookupContext, PropertyObject &  object, string_view  path  )

inline

Removes a local notification listener.

Parameters

lookupContext	Lookup context to use.
object	Object to listen on.
path	Path associated with lookup.

onGlobalLookupNotification()

virtual void kanzi::BindingLookupNotificationBase::onGlobalLookupNotification ( )

pure virtual

Called when global notification is triggered.

This usually means a target object may have become available.

Implemented in kanzi::TypedObjectPropertyBindingSourceRuntime< T >, and kanzi::TypedObjectPropertyExpressionValueSourceRuntime< T >.

onLocalLookupNotification()

virtual void kanzi::BindingLookupNotificationBase::onLocalLookupNotification ( )

pure virtual

Called when local notification is triggered.

This usually means a target object may have become unavailable.

Implemented in kanzi::TypedObjectPropertyBindingSourceRuntime< T >, and kanzi::TypedObjectPropertyExpressionValueSourceRuntime< T >.

Member Data Documentation

m_globalNotificationInstalled

bool kanzi::BindingLookupNotificationBase::m_globalNotificationInstalled

protected

Is the global notification listener installed?

m_localNotificationInstalled

bool kanzi::BindingLookupNotificationBase::m_localNotificationInstalled

protected

Is the local notification listener installed?
