Method Set

expr/types.go:473–481

Set replaces the object named attribute n if any - creates a new object by appending to the slice of named attributes otherwise. The resulting object is returned in both cases.

(n string, att *AttributeExpr)

// appending to the slice of named attributes otherwise. The resulting object is
// returned in both cases.
func (o *Object) Set(n string, att *AttributeExpr) {
	for _, nat := range *o {
		if nat.Name == n {
			nat.Attribute = att
			return
		}
	}
	*o = append(*o, &NamedAttributeExpr{n, att})
}

// Delete creates a new object with the same named attributes as o but without
// the named attribute n if any.
