If at least one of these offers is accepted, the offered tokens are removed from their original source and the acceptor receives a copy of the tokens. Next snippet Related snippets A ForkNode is a ControlNode that splits a flow into multiple concurrent flows. A ForkNode shall have exactly one incoming ActivityEdge, though it may have multiple outgoing ActivityEdges. If the incoming edge is a ControlFlow, then all outgoing edges shall be ControlFlows and, if the incoming edge is an ObjectFlow, then all outgoing edges shall be ObjectFlows. Related snippets (backlinks) However, the same token can only be accepted at one target at a time (unless it is copied, whereupon it is not the same token, see ForkNodes ... and ExecutableNodes ...). If a token is offered to multiple ActivityNodes at the same time, it shall be accepted by at most one of them, but exactly which one is not completely determined by the Activity flow semantics. This means that an Activity model in which non-determinacy occurs may be subject to timing issues and race conditions. It is the responsibility of the modeler to avoid such conditions in the construction of the Activity model, if they are not desired. Visit also Visit also (backlinks) Flags
