Next snippet Related snippets SysML provides extensions that might be very loosely grouped under the term “continuous,” but are generally applicable to any sort of distributed flow of information and physical items through a system. Extension of object nodes, including pins, with the option for newly arriving values to replace values that are already in the object nodes (see Overwrite in Figure 11-8). SysML also extends object nodes with the option to discard values if they do not immediately flow downstream (see NoBuffer in Figure 11-8).
