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.

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);
