Next snippet Whereas flow properties specify what “can” flow in or out of a block, item flows specify what “does” flow between blocks and/or parts in a particular usage context. Related snippets An ItemFlow describes the flow of items across a connector or an association. It may constrain the item exchange between blocks, block usages, or ports as specified by their flow properties. An ItemFlow describes the flow of items across a connector or an association. The notation of an item flow is a black arrowhead on the connector or association. The arrowhead is towards the target element. Connectors with item flows can be decomposed by association blocks that have additional item flows. The relationship between an item flow and those in the association block is determined by the modeler. Item flows in internal block diagrams specify flows local to a block. Related snippets (backlinks) Whereas flow properties specify what “can” flow in or out of a block, item flows specify what “does” flow between blocks and/or parts in a particular usage context. This important distinction enables blocks to be interconnected in different ways depending on its usage context. For example, tanks might include a flow property that can accept fluid as an input. In a particular use of tanks, “gasoline” flows across a connector into a tank, and in another use of tanks, “water” flows across a connector into a tank. The item flow in each case specifies what “does” flow on the connector in the particular usage (e.g., gas, water) and the flow property specifies what can flow (e.g., fluid). This enables type matching between the item flows and between flow properties... Visit also Visit also (backlinks) Flags
