Types

type EvaluatedSituation

type EvaluatedSituation struct {
	ID                 int64
	TS                 time.Time
	TemplateInstanceID int64
	Agenda             []ruleeng.Action
}

EvaluatedSituation represents the evaluation of a situation

func EvaluateObjectSituations

func EvaluateObjectSituations(situations []SituationToEvaluate, factObject engine.Fact, objects []map[string]interface{}, engineID string) ([]EvaluatedSituation, error)

EvaluateObjectSituations evaluates a slice of situations and return a slice with the evaluated situations

func EvaluateSituations

func EvaluateSituations(situations []SituationToEvaluate, engineID string) ([]EvaluatedSituation, error)

EvaluateSituations evaluates a slice of situations and return a slice with the evaluated situations

type SituationToEvaluate

type SituationToEvaluate struct {
	ID                 int64
	TS                 time.Time
	TemplateInstanceID int64
	Facts              []int64
	Parameters         map[string]string
}

SituationToEvaluate is used to notify a rule engine instance that a situation must me evaluated
