For object nodes that are the target of continuous flows, «overwrite» and «nobuffer» have the same effect. Source OMG Systems Modeling Language (SysML) 1.6
NoBuffer::1_not_overwrite The «nobuffer» and «overwrite» stereotypes cannot be applied to the same element at the same time Source OMG Systems Modeling Language (SysML) 1.6
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 ... Source OMG Systems Modeling Language (SysML) 1.6
For object nodes that are the target of continuous flows, «nobuffer» and «overwrite» have the same effect. Source OMG Systems Modeling Language (SysML) 1.6
This is typically used with fast or continuously flowing data values, to prevent buffer overrun, or to model transient values, such as electrical signals. Source OMG Systems Modeling Language (SysML) 1.6
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. Source OMG Systems Modeling Language (SysML) 1.6
These two extensions are useful for ensuring that the most recent information is available to actions by indicating when old values should not be kept in object nodes, and for preventing fast or continuously flowing values from collecting ... Source OMG Systems Modeling Language (SysML) 1.6
SysML also extends object nodes with the option to discard values if they do not immediately flow downstream (see NoBuffer in Figure 11-8). Source OMG Systems Modeling Language (SysML) 1.6
