* Existence of meta-model allows for better evolution of YANG language as it evolves * and allows for better support of different serializations of YANG model. * *
* Statements are represented as instances / subclasses of * {@link org.opendaylight.yangtools.yang.model.api.meta.ModelStatement} concept and its two subconcepts which are: *
* Clear separation of declared / effective model is needed, since statement definition also * contains information how effective model is computed and there is no one to one mapping * between declared and effective model thanks to statements such as {@code uses}, * {@code augment},{@code deviate},{@code refine}. * *
* Common abstraction for various types of namespaces is * {@link org.opendaylight.yangtools.yang.model.api.meta.IdentifierNamespace} * from which concrete effective model namespaces are derived. */ package org.opendaylight.yangtools.yang.model.api.meta;
