Detailed Description

This listens an event, and can be subscribed by a process or a gated variable it is aimed at being used internally to a module to store a reference to an event emitted by another module, or an internal event expression. Then only one process or a gated variable at once can be sensitive to this listener. In case of doubt,you should prefer EventListener which has a similar behavior, but no constraints on the number of sensitivity The rationale for EventListenerSingle is that it is very slightly more efficient than an EventListener

virtual void Sampa::Object::complete_restart

(

)

[protected, virtual, inherited]

is called to finalize restart. On restart, one shall update pointers, or reopen ressources (files, ...).

Most of pointers are restored by the thanks to the post++ library provided that the CLASSINFO() was correctly set.

However, some pointers are not relocated by the library. These are for example the method pointers used for the processes. Take a look at

Reimplemented in Sampa::Bridge, Sampa::Dma, Sampa::FixLatencySlave, Sampa::PeriodicTrafficGenerator, Sampa::TwoPortL1Cpu, and Sampa::StochasticCpu.
