Which of the following is a True statement regarding the Builder?

The statement about the Builder calling the Formatter after storing the internal message is indeed true. In the context of the Avaloq Message Interface, the Builder's primary role is to construct messages that can be transmitted within the system. Once it has composed the internal representation of a message, it will then invoke the Formatter to ensure the message is formatted properly for transmission. This step is crucial because it allows the data to be presented in a structure compatible with the receiving systems, maintaining integrity and ensuring smooth communication.

This function highlights the relationship between the Builder and Formatter, illustrating the sequential workflow where the Builder constructs the data and the Formatter readies it for distribution. Understanding this relationship is key in grasping how message composition and transmission are handled within the Avaloq environment.
