示例1: processPredicate
// processPredicate updates the working graph clause if there is an available
// predicate.
func processPredicate(c *GraphClause, ce ConsumedElement, lastNopToken *lexer.Token) (*predicate.Predicate, string, string, bool, error) {
var (
nP *predicate.Predicate
pID string
pAnchorBinding string
temporal bool
)
raw := ce.Token().Text
p, err := predicate.Parse(raw)
if err == nil {
// A fully specified predicate was provided.
nP = p
return nP, pID, pAnchorBinding, nP.Type() == predicate.Temporal, nil
}
// The predicate may have a binding on the anchor.
cmps := predicateRegexp.FindAllStringSubmatch(raw, 2)
if len(cmps) != 1 || (len(cmps) == 1 && len(cmps[0]) != 3) {
return nil, "", "", false, fmt.Errorf("failed to extract partialy defined predicate %q, got %v instead", raw, cmps)
}
id, ta := cmps[0][1], cmps[0][2]
pID = id
if ta != "" {
pAnchorBinding = ta
temporal = true
}
return nil, pID, pAnchorBinding, temporal, nil
}示例2: CheckAndUpdate
// CheckAndUpdate checks if a predicate should be considered and it also updates
// the internal state in case counts are needed.
func (c *checker) CheckAndUpdate(p *predicate.Predicate) bool {
if c.max {
if c.c <= 0 {
return false
}
c.c--
}
if p.Type() == predicate.Immutable {
return true
}
t, _ := p.TimeAnchor()
if c.o.LowerAnchor != nil && t.Before(*c.o.LowerAnchor) {
return false
}
if c.o.UpperAnchor != nil && t.After(*c.o.UpperAnchor) {
return false
}
return true
}
