Functions

func EventScore

func EventScore(e models.Event) int

Determine the score of an event. An event with higher score should be emitted before lower ones. The score based ordering ensures continuous routability, so events with running instances should be emitted first followed by remove events.

Types

type ActualLRPEventCalculator

type ActualLRPEventCalculator struct {
	ActualLRPGroupHub    events.Hub // DEPRECATED
	ActualLRPInstanceHub events.Hub
}

func (ActualLRPEventCalculator) EmitEvents

func (e ActualLRPEventCalculator) EmitEvents(beforeSet, afterSet []*models.ActualLRP)

EmitEvents emits the events such as when the changes identified in the events are applied to the beforeSet the resulting state is equal to afterSet. The beforeSet and afterSet are assumed to have the same process guid and index.

func (ActualLRPEventCalculator) RecordChange

func (e ActualLRPEventCalculator) RecordChange(before, after *models.ActualLRP, lrps []*models.ActualLRP) []*models.ActualLRP

RecordChange returns a new LRP set with the before LRP replaced with after LRP. The index of after and before is the same. New LRPs (i.e. when before is nil) are appended to the end of the lrp slice.
