Detailed Description

template<typename... Args>
class osmscout::Signal< Args >

Signal and Slot is tool for connecting source of events and its consumers. It is similar to Qt's signal, but it lacks some advanced functionality, like asynchronous connection. Slot callback is called in thread context of the signal. Locking or asynchronicity have to be solved differently.

Signal and Slot are thread safe. Their live cycle may be independent.
