References KPlato::Schedule::endTime, and KPlato::Node::m_currentSchedule.

Duration KPlato::Task::positiveFloat (  ) 

Return the duration that an activity's start can be delayed without affecting the project completion date. An activity with positive float is not on the critical path.

Duration KPlato::Task::negativeFloat (  )  [inline]

Return the duration by which the duration of an activity or path has to be reduced in order to fullfill a timing constraint.

Definition at line 225 of file kpttask.h.

Duration KPlato::Task::freeFloat (  )  [inline]

Return the duration by which an activity can be delayed or extended without affecting the start of any succeeding activity.

Duration KPlato::Task::startFloat (  )  [inline]

Return the duration from Early Start to Late Start.

Definition at line 234 of file kpttask.h.

Duration KPlato::Task::finishFloat (  )  [inline]

Return the duration the task has at its finish before a successor task starts. This is the difference between the start time of the successor and the finish time of this task.
