Full quote The stereotype does not override UML token offering semantics; it just indicates what happens to the token when it is accepted. When the stereotype is not applied, the semantics are as in UML, specifically, tokens arriving at an object node that are refused by outgoing edges, or action for input pins, are held until they can leave the object node. Next snippet Related snippets When the «nobuffer» stereotype is applied to object nodes, tokens arriving at the node are discarded if they are refused by outgoing edges, or refused by actions for object nodes that are input pins. This is typically used with fast or continuously flowing data values, to prevent buffer overrun, or to model transient values, such as electrical signals. For object nodes that are the target of continuous flows, «nobuffer» and «overwrite» have the same effect.
