Detailed Description

Member Typedef Documentation

◆ Handler

template<typename classT , typename dataT = void>
using SST::Event::Handler = SSTHandler<void, Event*, classT, dataT>

Used to create handlers for event delivery.

The callback function is expected to be in the form of:

void func(Event* event)

In which case, the class is created with:

new Event::Handler<classname>(this, &classname::function_name)

Or, to add static data, the callback function is:

void func(Event* event, dataT data)

and the class is created with:

new Event::Handler<classname, dataT>(this, &classname::function_name, data)

Member Function Documentation

◆ clone()

Event * SST::Event::clone ( )
virtual

Clones the event in for the case of a broadcast.

Reimplemented in SST::Interfaces::StringEvent.

References SST::Output::fatal(), SST::Simulation_impl::getSimulation(), and SST::Simulation_impl::getSimulationOutput().

◆ serialize_order()

void SST::Event::serialize_order ( SST::Core::Serialization::serializer ser)
inlineoverridevirtual

Reimplemented from SST::Activity.
