All Implemented Interfaces:

ConfIterate, MaapiDiffIterate

Direct Known Subclasses:

NavuListEntry
```
public class NavuContainer
extends NavuNode
implements MaapiDiffIterate
```
NavuContainer is a representation of the yang construct container,module and list-entry.
A NavuContainer is usually supplied or returned from a method call. It can also be created using one of its constructors, typically NavuContainer(NavuContext). A NavuContainer is created with a NavuContext initialized with a Maapi socket:
```
   NavuContext context = new NavuContext(maapi);
   context.startRunningTrans(Conf.MODE_READ_WRITE);
   NavuContainer root = new NavuContainer(context);
 
```
As shown above, a transaction must be started before the context can be used for navigating.
A transaction can alternatively be started for operational data instead:
```
   NavuContext context = new NavuContext(maapi);
   context.startOperationalTrans(Conf.MODE_READ_WRITE);
   NavuContainer root = new NavuContainer(context);
 
```
Either way, when a NavuContainer is created using the above mentioned context, the object pointed to by root is the "root" of the NAVU-Tree.
The root's children represent all of the loaded modules. To choose a particular module, the method NavuContainer.container(Integer) must be called with the hash value of the corresponding module (ConfNamespace.hash()). This will return a new NavuContainer pointing to the root of the chosen module.
```
   NavuContainer module = root.container(new Ncs().hash());
 
```
To continue further down to the next child, use NavuContainer.container(Integer), NavuContainer.container(String), NavuContainer.list(Integer), NavuContainer.list(String) or NavuContainer.leaf(Integer), NavuContainer.leaf(String) as dictated by the YANG model. The string version is the corresponding MaapiSchemas.hashToString(long) of the Integer parameter which is the hash value of the tag name.
Usually the generated namespace classes static method are used for convenience. The absence of underscore (_) at the end of the static field name indicates the integer version.
Then continuing with the devices node:
```
   NavuContainer devicesNode = module.container(Ncs._devices);
```

    Creates an optional container.
    Will silently ignore the error when the container is not a presence container. It will also maintain a counter (as an attribute) counting how many times the same containers has been created.

Furthermore, and attribute "Backpointer" will be created on the created container indicating which "service" created the object

```
    Description copied from class: NavuNode
    Encodes the sub-tree including the current NavuNode as the topmost NavuNode as a ConfXMLParam array.
    The returned ConfXMLParam array contains no values except for list keys. The leaf elements are encoded as ConfXMLParamLeaf. Therefore, the returning array can be used as a the input parameter to NavuNode.getValues(ConfXMLParam[]) on the current node's parent.
    NavuNode node = ...; ConfXMLParam[] cxa = node.encodeXML().toArray(new ConfXMLParam[0]); // cxa contains a structure that does not contain values except for // keys in list elements NavuNode parent = node.getParent(); ConfXMLParam[] cxb = parent.getValues(cxa); // cxb contains the same sub-tree with all the values
    Specified by:

```
    Analyzes what changes has been done within this transaction. The prerequisites are:
    - This is the container of a module.
    - That this container has been created using two MAAPI sockets.
    Since deletes are already removed in current transactions a delete context is necessary to retrieve information about delete changes.
    The delContext is a NavuContext with a read transaction on the running database to read deletes. If null delete changes will not be able to be retrieved.
    Parameters:
    
    delContext - NavuContext to retrieve deleted values with.
    
    criteria - a list hash values representing a search path. The first element is the module name hash. The analysis will be started at the end of the list. List elements are represented by 0.

    Deprecated. Use the method NavuContainer.setOperDataCase(String , String)
    
    There is a difference in how cases for a choice is set in a Maapi context and a Cdb context. In Maapi, when writing configuration data, the cases are set implicitly as any leaf are set below a choice in the model tree. For Cdb, when writing operational data, this case has to be set explicitly. This is done using this method. The method returns a NavuContainer representing the selected case which can be used to navigate down the model tree.
    
    Parameters:
    
    choiceStr - name of the choice
    
    caseStr - name of the case to set as selected case
    
    Returns:

    Set a case with the name caseStr for a choice choiceStr for Cdb when writing operational data. There is a difference in how cases for a choice is set in a Maapi context and a Cdb context.

    Parameters:
    
    choiceStr - name of the choice
    
    caseStr - name of the case to set as selected case
    
    Throws:
    
    NavuException - If the caseStr could not be set
  - equals
```
public boolean equals(Object o)
```
    Compares the specified object with this NavuContainer for equality. Returns true if the specified object is also a NavuContainer and either of the following is true:
    - Both nodes are modules according to NavuNodeInfo.isModule()) and they have the same namespace URI.
    - The nodes are not modules, and have identical ConfPath instances.
    Specified by:
    
    equals in class NavuNode
    
    Parameters:
    
    o - the object to be compared for equality with this NavuContainer
