Detailed Description

Abstract interface for VariableBindingSources and VariableExpressionValueSource.

Implements notification interface for VariableBindingTarget state changes being notified to connected sources.

Since

Kanzi 3.9.0

Member Function Documentation

setTargetRuntime()

void kanzi::AbstractBindingVariableSource::setTargetRuntime ( VariableBindingTargetRuntime * targetRuntime )

inline

Sets the variable binding target runtime.

Only called by VariableBindingTargetRuntime upon connection and disconnection.

Parameters

targetRuntime

Variable target runtime connected to.

getPropertyType()

AbstractPropertyType kanzi::AbstractBindingVariableSource::getPropertyType ( ) const

inline

Gets the associated property type for this variable source.

Returns

Property type.

notifyVariableAvailable()

void kanzi::AbstractBindingVariableSource::notifyVariableAvailable ( )

inline

Notification function for when variable has become available or has been changed.

Called by VariableBindingTargetRuntime for each connected variable source.

notifyVariableDetached()

void kanzi::AbstractBindingVariableSource::notifyVariableDetached ( )

inline

Notification function for when variable has become detached and is no longer available.

Called by VariableBindingTargetRuntime for each connected variable source.

getPropertyTypeOverride()

virtual AbstractPropertyType kanzi::AbstractBindingVariableSource::getPropertyTypeOverride ( ) const

protectedpure virtual

Implementation-dependent property type acquire.

Returns

Property type.

Implemented in kanzi::VariableBindingSourceRuntime, and kanzi::VariableExpressionValueSourceRuntime.

notifyVariableAvailableOverride()

virtual void kanzi::AbstractBindingVariableSource::notifyVariableAvailableOverride ( )
