Functions

func BuildFilters 

func BuildFilters(str string, fields map[string]func(p proto.Message) string) ([][]Filter, error)

BuildFilters creates a set of filters based on an input string. Within the field map, SCIM path names are expected to be lowercase. Example: 

BuildFilters(`name.formatted eq "Joe" or name.familyName sw "Smith"`, map[string]func(p proto.Message) string {
  "name.formatted": func(p proto.Message) string {
    return myProtoCast(p).Profile.Name
  },
  "name.familyname": func(p proto.Message) string {
    return myProtoCast(p).Profile.FamilyName
  },
})

The filters generated by this method can be evaluated with a proto input using MatchProtoFilters(filters, myProto).

func ErrNotFound 

func ErrNotFound(err error) bool

func GetHistory 

func GetHistory(store Store, datatype, realm, user, id string, r *http.Request) (*cpb.History, int, error)

GetHistory returns a History object based on the input parameters.

func MakeConfigHistory 

func MakeConfigHistory(desc, resType string, rev int64, ts float64, r *http.Request, user string, orig, update proto.Message) proto.Message

func MatchProtoFilters 

func MatchProtoFilters(cnfFilters [][]Filter, p proto.Message) bool

MatchProtoFilters returns true if any of the filter conditions are met (i.e. evaluates a Conjunctive Normal Form (CNF) of this array of filters). Simplified version of: https://tools.ietf.org/html/rfc7644#section-3.4.2.2

func ReplaceContentVariables added in v0.8.4 

func ReplaceContentVariables(content proto.Message, varValues map[string]string) error

ReplaceContentVariables does simple string replacement of variable names to values. If varValues is nil, then it only checks that `content` is JSON.

func UserFragment 

func UserFragment(user string) string
