Member Function Documentation

PriorityDiscipline::ComparatorPointer PriorityDiscipline::getComparator ( )

protectedvirtual

return a function pointer to a function that provides comparison of tasks' priorities

Returns

a pointer to a function taking two processes as arguments, and returning a boolean value. The return value is true if the first argument task's priority is higher than the second one.

Reimplemented in Scheduler::RmsDiscipline, and Scheduler::EdfDiscipline.

Definition at line 62 of file priorityDiscipline.cpp.

virtual std::string Scheduler::PriorityDiscipline::getName ( )

pure virtual

returns the name of that discipline

Implements Scheduler::SchedulingDiscipline.

Implemented in Scheduler::RmsDiscipline, Scheduler::EdfDiscipline, and Scheduler::FixedPriorityDiscipline.

bool PriorityDiscipline::preempts ( TriggeringEvent  trigger )

virtual

returns true if the argument is a scheduling trigger for this specific discipline

Parameters

trigger

the type of the event that triggered the scheduling invokation

Implements Scheduler::SchedulingDiscipline.

Definition at line 40 of file priorityDiscipline.cpp.

std::shared_ptr< Process > PriorityDiscipline::selectNextTask ( Queue *  readyQueue, std::shared_ptr< Process >  running, unsigned  deadlineMisses  )

virtual

select the best task to run at this point.

Parameters

readyQueue	the ready queue
running	the currently running task
deadlineMisses

Returns

the next task to be run

Implements Scheduler::SchedulingDiscipline.

Definition at line 21 of file priorityDiscipline.cpp.

void PriorityDiscipline::updatePriorities ( Queue *  readyQueue, std::shared_ptr< Process >  running  )

protectedvirtual

sets the correct priorities to the tasks, especially if dynamic priorities are used.

Reimplemented in Scheduler::FixedPriorityDiscipline.

Definition at line 46 of file priorityDiscipline.cpp.
