[Yang 1.1] Allow leaf-lists to have default values

Bug Resolved Done Peter Kajsa Peter Kajsa Thu, 6 Oct 2016 08:54:53 +0000 Sun, 10 Apr 2022 18:35:53 +0000 Wed, 21 Dec 2016 13:18:22 +0000 0 2 <p>RFC7950:</p> <p>7.7.2. The leaf-list’s Default Values<br/> The default values of a leaf-list are the values that the server uses<br/> if the leaf-list does not exist in the data tree. The usage of the<br/> default values depends on the leaf-list’s closest ancestor node in<br/> the schema tree that is not a non-presence container (see<br/> Section 7.5.1):<br/> o If no such ancestor exists in the schema tree, the default values<br/> MUST be used.<br/> o Otherwise, if this ancestor is a case node, the default values<br/> MUST be used if any node from the case exists in the data tree or<br/> the case node is the choice’s default case, and if no nodes from<br/> any other case exist in the data tree.<br/> o Otherwise, the default values MUST be used if the ancestor node<br/> exists in the data tree.<br/> In these cases, the default values are said to be in use.<br/> Note that if the leaf-list or any of its ancestors has a "when"<br/> condition or "if-feature" expression that evaluates to "false", then<br/> the default values are not in use.<br/> When the default values are in use, the server MUST operationally<br/> behave as if the leaf-list was present in the data tree with the<br/> default values as its values.<br/> If a leaf-list has one or more "default" statements, the leaf-list’s<br/> default values are the values of the "default" statements, and if the<br/> leaf-list is user ordered, the default values are used in the order<br/> of the "default" statements. Otherwise, if the leaf-list’s type has<br/> a default value and the leaf-list does not have a "min-elements"<br/> statement with a value greater than or equal to one, then the<br/> leaf-list’s default value is one instance of the type’s default<br/> value. In all other cases, the leaf-list does not have any default<br/> values.</p> <p>API change - <a href="https://git.opendaylight.org/gerrit/#/c/47985/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/47985/</a></p> <p><a href="https://git.opendaylight.org/gerrit/#/c/49473/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/49473/</a></p> Blocks YANGTOOLS-355 YANGTOOLS-664 YANGTOOLS-699 Development External issue ID 6880 External issue URL Issue Type ODL SR Target Milestone Rank 0|i028p3:
