Detailed Description

template<typename TArgumentsClass>
class kanzi::DynamicMessageType< TArgumentsClass >

DynamicMessageType is a handle to an existing message type.

You can use it to add and remove a message handler or to dispatch a message of that type on a node.

You can use a DynamicMessageType to access message types when you have their message arguments and fully qualified name. When you do not have a fully qualified name or message arguments of a message type, or they are irrelevant, to access message types, use the AbstractMessageType type.

See also: To learn how to create a Kanzi message type, see MessageType.

Examples

To create for an existing message type a DynamicMessageType with a fully qualified name:

// You can create a dynamic message type handle to an existing message type by using the fully qualified name.

DynamicMessageType<ButtonConcept::ClickedMessageArguments> clickedMessage("Message.Button.Click");

To add a message handler with DynamicMessageType:

        // To add and remove message handlers, you need either:
        // - DynamicMessageType object that refers to an existing message type.
        // - MessageType object. For example, ButtonConcept::ClickedMessage.
        Node::MessageSubscriptionToken token = node->addMessageHandler(clickedMessage, node.get(), &ExampleNode2D::exampleCallback);

Constructor & Destructor Documentation

template<typename TArgumentsClass >

kanzi::DynamicMessageType< TArgumentsClass >::DynamicMessageType ( string_view name )

inlineexplicit

Constructor.

Creates a DynamicMessageType instance that refers to the same existing message type as the given name.

Parameters

name	Fully qualified name of an existing message type in the Kanzi message system.

Exceptions

logic_error if there is no message type with the given name in the Kanzi message system or the message arguments do not match the existing message type with the given name.

template<typename TArgumentsClass >

kanzi::DynamicMessageType< TArgumentsClass >::DynamicMessageType ( AbstractMessageType abstractMessageType )

inlineexplicit

Constructor.

Creates a DynamicMessageType instance that refers to the same existing message type as the given AbstractMessageType instance does.

Parameters

abstractMessageType AbstractMessageType instance that refers to the existing message type in the Kanzi message system.

Exceptions

logic_error if the message arguments do not match the existing message type to which the given AbstractMessageType refers or if the given AbstractMessageType is null.

template<typename TArgumentsClass >
