Detailed Description

template<typename C>
class inviwo::Dispatcher< C >

Dispatches functions to a number of callbacks and cleans up callbacks when they are dead. Thread-safe via copy-on-write semantics on the callback vector.

• add() is implemented with a CAS loop that copies the callback vector, appends the new callback and attempts to swap it in.
• invoke() performs a single load of the callback vector and invokes all live callbacks. No locks are held during invocation.
