DescriptionYangJava Object ViewNotes

Datatypes and basic constraints

Basic String

leaf response-code {
  type string;
}

Datatypes validated by XmlParser
Mandatory Basic String

leaf response-code {
  type string;
    mandatory "true";
}

Mandatory NOT checked by XmlParser
Limited String leaf pnf-name {
  type string {
    length "0..256";
}

Specialized class to hold length limitation

Checked by XmlParser


typedef (String) with pattern

typedef dotted-quad {
  type string {
pattern
  '(([0-9] ...';
  }
}

leaf address {
   type dotted-quad;
   mandatory "true";
}

Checked by XmlParser
Limited unint64 leaf cid {
  type string {
  length "0..52";
}


boolean with default value

leaf blacklisted {
  type boolean;
  default 1;
}


Unique

Unique list server {
  key "name";
  unique "ip port";
  leaf name {
    type string;
  }
  leaf ip {
    type dotted-quad;
  }
  leaf port {
    type uint32;
  }}

NOT checked by XmlParser

Choice

Choicechoice transfer-method {
  leaf transfer-interval {
    type uint64 { range "15..2880"; }
    units minutes; }
  leaf transfer-on-commit {
  type empty;
  }}


Must

Must leaf ifType {
type enumeration {
enum ethernet;
enum atm;}}
leaf ifMTU {
type uint32;}
must "ifType != 'ethernet' or "
+ "(ifType = 'ethernet' and ifMTU = 1500)" {error-message 466px"An ethernet MTU must be 1500";}


When

When
leaf a {
    type boolean;
}
leaf b {
    type string;
    when "../a = 'true'";
}


Extension

Extension declaration extension store-state-ext {
argument duration;
description "An extension to enable state-storage for any attribute. Use duration to specify how long: nnn h|d|y";
}


Extension usage leaf attribute-with-temporal-storage {
  type string;
  cm-notify-api:store-state-ext "3 d"; // store state 3 days
}

extension is stored as 'UnknownNode' and refers back to the extension declaration

Augmentation


 augment "server" {
  when "port = '8787'";
    leaf enable-debug {
      type boolean;
    }
}
