The goal of this example is to show how to use Composite Entity Creator block for resource allocation. You can combine entities from different paths using the Composite Entity Creator block. The entities that you combine, called composite entities, might represent different parts within a larger item, such as the header, payload, and trailer that are parts of a data packet. Alternatively, you can model resource allocation by combining an entity that represents a resource with an entity that represents a part or other item.
The Composite Entity Creator block detects when all necessary component entities are present and when the composite entity that results from the combining operation will be able to advance to the next block. The Composite Entity Creator block provides options for managing information (attributes and timers) associated with the component entities. You can also configure the Composite Entity Creator block to make the combining operation reversible via the Composite Entity Splitter block.
