Detailed Description

A Clock class.

Calls callback functions (handlers) on a specified period

Member Typedef Documentation

◆ Handler

template<typename classT , typename dataT = void>
using SST::Clock::Handler = SSTHandler<bool, Cycle_t, classT, dataT>

Used to create handlers for clock.

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

bool func(Cycle_t cycle)

In which case, the class is created with:

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

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

bool func(Cycle_t cycle, dataT data)

and the class is created with:

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

In both cases, the boolean that's returned indicates whether the handler should be removed from the list or not. On return of true, the handler will be removed. On return of false, the handler will be left in the clock list.

Member Function Documentation

◆ toString()

std::string SST::Clock::toString ( ) const
overridevirtual

Get a string represenation of the event.

The default version will just use the name of the class, retrieved through the cls_name() function inherited from the serialzable class, which will return the name of the last class to call one of the serialization macros (ImplementSerializable(), ImplementVirtualSerializable(), or NotSerializable()). Subclasses can override this function if they want to add additional information.

Reimplemented from SST::Activity.
