Full quote In some cases, multiple concurrent executions of an ExecutableNode may be ongoing at one time (see the semantics of isLocallyReentrant=true for Actions in sub clause 16.2). In this case, the ExecutableNode holds one control token for each concurrent execution. Next snippet Related snippets A ControlFlow is an ActivityEdge traversed by control tokens or object tokens of control type, which are use to control the execution of ExecutableNodes no_executable_nodes ObjectFlows may not have ExecutableNodes at either end. An ExecutableNode is a kind of ActivityNode that may be executed as a step in the overall desired behavior of the containing Activity. All concrete kinds of ExecutableNodes are Actions ... An ExecutableNode is an ActivityNode that carries out a substantive behavioral step of the Activity that contains it. An ExecutableNode may also consume and produce data, but it must do so through related ObjectNodes (Actions use Pins for this purpose ... An ExecutableNode shall not execute until all incoming ControlFlows (if any) are offering tokens. That is, there is an implicit join on the incoming Control Flows. Specific kinds of ExecutableNodes may have additional prerequisites ... Before an ExecutableNode begins executing, it accepts all tokens offered on incoming ControlFlows. If multiple tokens are being offered on a ControlFlow, they are all consumed. While the ExecutableNode is executing, it is considered to hold a single control [token] indicating it is execution [executing]. Related snippets (backlinks) Visit also Visit also (backlinks) Flags
