+ * Event Stream Writer for Binding Representation
+ *
+ *
+ * <h3>Emmiting Event Stream</h3>
+ *
+ * <ul>
+ * <li><code>container</code> - Container node representation, start event is
+ * emitted using {@link #startContainerNode(Class, int)} and node end event is
+ * emitted using {@link #endNode()}. Container node is implementing
+ * {@link DataObject} interface.
+ *
+ * <li><code>list</code> - YANG list statement has two representation in event
+ * stream - unkeyed list and map. Unkeyed list is YANG list which did not
+ * specify key.</li>
+ *
+ * <ul>
+ * <li><code>Map</code> - Map start event is emitted using
+ * {@link #startMapNode(Class, int)} and is ended using {@link #endNode()}. Each map
+ * entry start is emitted using {@link #startMapEntryNode(Identifier, int)} with Map of keys
+ * and finished using {@link #endNode()}.</li>
+ *
+ * <li><code>UnkeyedList</code> - Unkeyed list represent list without keys,
+ * unkeyed list start is emmited using {@link #startUnkeyedList(Class, int)} list
+ * end is emmited using {@link #endNode()}. Each list item is emmited using
+ * {@link #startUnkeyedListItem()} and ended using {@link #endNode()}.</li>
+ * </ul>
+ *
+ * <li><code>leaf</code> - Leaf node event is emitted using
+ * {@link #leafNode(String, Object)}. {@link #endNode()} MUST be not emmited for
+ * leaf node.</li>
+ *
+ * <li><code>leaf-list</code> - Leaf list start is emitted using
+ * {@link #startLeafSet(String, int)}. Leaf list end is emitted using
+ * {@link #endNode()}. Leaf list entries are emmited using
+ * {@link #leafSetEntryNode(Object).
+ *
+ * <li><code>anyxml - Anyxml node event is emitted using
+ * {@link #leafNode(String, Object)}. {@link #endNode()} MUST be not emmited
+ * for anyxml node.</code></li>
+ *
+ *
+ * <li><code>choice</code> Choice node event is emmited by
+ * {@link #startChoiceNode(Class, int)} event and must be immediately followed by
+ * {@link #startCase(Class, int)} event. Choice node is finished by emitting
+ * {@link #endNode()} event.</li>
+ *
+ * <li>
+ * <code>case</code> - Case node may be emitted only inside choice node by
+ * invoking {@link #startCase(Class, int)}. Case node is finished be emitting
+ * {@link #endNode()} event.</li>
+ *
+ * <li>
+ * <code>augment</code> - Represents augmentation, augmentation node is started
+ * by invoking {@link #startAugmentationNode(Class)} and
+ * finished by invoking {@link #endNode()}.</li>
+ *
+ * </ul>
+ *
+ * <h3>Implementation notes</h3> This interface is not intended to be
+ * implemented by users of generated Binding DTOs but to be used by utilities,
+ * which needs to emit NormalizedNode model from Binding DTOs.
+ * <p>
+ * This interface is intended as API definition of facade for real Event /
+ * Stream Writer, without explicitly requiring stream writer and related
+ * interfaces to be imported by all generated Binding DTOs.
+ * <p>
+ * Existence of this interface in base Java Binding package is required to
+ * support runtime generation of users of this interface in OSGI and OSGI-like
+ * environment, since this package is only package which is imported by all
+ * generated Binding DTOs and wired in OSGI.
