Composite Entity Creator

Description

The Composite Entity Creator block creates a composite entity for each set of entities arriving simultaneously at all input ports. The newly created entity can include information about the structure, attributes, and timers of the arriving entities.

You can combine entities from different paths using this block. The combined entity represents 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. You can also configure the Composite Entity Creator block to make the combining operation reversible via the Composite Entity Splitter block.

Examples

Match Entities Based on Attributes

Build a model to store and match entities representing bicycle components. The model uses an Entity Store block for storage and an Entity Selector block to match a set of bicycle wheels to the corresponding size frame for assembly.
