Detailed Description

ForwardingApplyAction is the base class for the ApplyAction classes that read and send an argument, such as ApplyPropertyAction.

ForwardingApplyAction contains functionality to read an argument from sources, such as messages, properties or set values, and allows the inheriting action class to use these values. This usually means sending messages or setting values of properties.

Since
Kanzi 3.9.0

Constructor & Destructor Documentation

◆ ForwardingApplyAction()

kanzi::ForwardingApplyAction::ForwardingApplyAction ( Domain domain,
string_view  name 
)
explicitprotected

Creates a ForwardingApplyAction.

Parameters
domainDomain to use.
nameName of this action instance.

Member Function Documentation

◆ addValueBinding()

void kanzi::ForwardingApplyAction::addValueBinding ( const Variant sourceValue,
AbstractPropertyType  targetArgument,
PropertyField  targetField 
)

Adds a binding from a value to a node or a message argument.

Use this function to set constant value to the sent message. Note that successive actions can override this value. You can retrieve the binding by calling getBindingInfo().

Parameters
sourceValueSource value.
targetArgumentTarget argument property type for the forwarded value.
targetFieldTarget property field of the argument property type.

◆ addArgumentBinding() [1/2]

void kanzi::ForwardingApplyAction::addArgumentBinding ( AbstractPropertyType  sourceArgument,
AbstractPropertyType  targetArgument 
)

Adds a binding from a message argument to a node or a message argument.

Use this function to bind from a source message argument to a target message argument. Both source and target property fields are PropertyFieldWhole. You can retrieve the binding by calling getBindingInfo().

Parameters
sourceArgumentSource message argument.
targetArgumentTarget argument property type for the forwarded value.

◆ addArgumentBinding() [2/2]

void kanzi::ForwardingApplyAction::addArgumentBinding ( AbstractPropertyType  sourceArgument,
PropertyField  sourceField,
AbstractPropertyType  targetArgument,
PropertyField  targetField 
)

Adds a binding from a message argument to a node or a message argument.

Use this function to bind from a source message argument to a target message argument. Source property field is PropertyFieldWhole. You can retrieve the binding by calling getBindingInfo().

Parameters
sourceArgumentSource message argument.
sourceFieldProperty field in the source argument property type.
targetArgumentTarget argument property type for the forwarded value.
targetFieldProperty field in the target argument property type.

◆ addPropertyBinding() [1/2]

void kanzi::ForwardingApplyAction::addPropertyBinding ( string_view  sourceObjectPath,
AbstractPropertyType  sourcePropertyType,
AbstractPropertyType  targetArgument 
)

Adds a binding from a property to a node or a message argument.

Use this function to bind from source object properties to a target message argument. The source object is a Node or a RenderPass object. Target property field is PropertyFieldWhole. You can retrieve the binding by calling getBindingInfo().

Parameters
sourceObjectPathPath to source object.
sourcePropertyTypeSource property type.
targetArgumentTarget argument property type for the forwarded value.

◆ addPropertyBinding() [2/2]

void kanzi::ForwardingApplyAction::addPropertyBinding ( string_view  sourceObjectPath,

PropertyField  sourceField,
AbstractPropertyType  targetArgument,
PropertyField  targetField 
)

Adds a binding from a property to a node or a message argument.

Use this function to bind from source object properties to target object properties. The function takes the path to the target node from the TargetObjectPathProperty. The source and target object is a Node or a RenderPass object. You can retrieve the binding by calling getBindingInfo().

Parameters
sourceObjectPathPath to source object.
sourcePropertyTypeSource property type.
sourceFieldProperty field in the source argument property type.
targetArgumentTarget argument property type for the forwarded value.
targetFieldProperty field in the target argument property type.

◆ addResourceBinding() [1/2]

void kanzi::ForwardingApplyAction::addResourceBinding ( ResourceID  id,
AbstractPropertyType  targetArgument,
PropertyField  targetField 
)

Adds a binding from a resource ID to a property.

Use this function to bind resolve resources to a target message argument. You can retrieve the binding by calling getBindingInfo().

Parameters
idResource ID.
targetArgumentTarget argument property type for the forwarded value.
targetFieldProperty field in the target argument property type.

◆ addResourceBinding() [2/2]

void kanzi::ForwardingApplyAction::addResourceBinding ( string_view  id,
AbstractPropertyType  targetArgument,
PropertyField  targetField 
)

Adds a binding from a resource ID to a property in a node.

Use this function to bind resolve resources to a target message argument. You can retrieve the binding by calling getBindingInfo().

Parameters
idName of the resource ID.
targetArgumentTarget argument property type for the forwarded value.
targetFieldProperty field in the target argument property type.

◆ load()

void kanzi::ForwardingApplyAction::load ( KzbFile kzbFile,
KzbMemoryParser parser 
)
overridevirtual

Action::load() implementation.

Reimplemented from kanzi::ActionBase.

◆ getBindingInfo()

optional<BindingInfo> kanzi::ForwardingApplyAction::getBindingInfo ( ) const

Returns the Binding information that this ForwardingApplyAction stores.

Returns
The Binding information that this ForwardingApplyAction stores.

◆ onCopy()

void kanzi::ForwardingApplyAction::onCopy ( const ForwardingApplyAction other)
protected

Deriving classes must call this function when creating instances of ForwardingApplyAction inside implementations of clone().

Parameters
otherSource ForwardingApplyAction from which to copy.
See also
Action::clone()

◆ loadBinding()

void kanzi::ForwardingApplyAction::loadBinding ( KzbFile kzbFile,
KzbMemoryParser parser 
)
protected

Loads a binding from a kzb file.

Parameters
kzbFileA kzb file from which you want to load a binding.
parserThe kzb file parser to use.

◆ removeBinding()

void kanzi::ForwardingApplyAction::removeBinding ( )
protected

Remove the stored binding information.

Member Data Documentation

◆ m_bindingInfo

optional<BindingInfo> kanzi::ForwardingApplyAction::m_bindingInfo
