typedef _Sequence::const_reference const_reference

Public Functions

bool eraseExpiredEvents()

remove expired events from the queue.

bool hasCurrentEvents()

are any events current (delay == 0 and triggered or persistant)

uint size() const

number of events in the queue

const_reference top()

The queue is re-sorted.

double getNextPendingEventTime()

the time the next event is sceduled to be assigned.

void saveState(std::ostream &out)

void loadState(std::istream &in, LLVMExecutableModel &model)
