  Parameters:
    `cache` - the cache to which this node belongs, required in case this node needs to use the cache; may not be null

    `NodeNotFoundException` - if this node does not exist anymore
  See Also:
    `getName(NodeCache)`, `getSegment(NodeCache)`

### getParentKey

    NodeKey getParentKey(NodeCache cache)

  Get the node key for this node's primary parent.

  Parameters:
    `cache` - the cache to which this node belongs, required in case this node needs to use the cache; may not be null
  Returns:
    the parent's key; null if this is the root node or it has been removed from the document by someone else

### getAdditionalParentKeys

    Set<NodeKey> getAdditionalParentKeys(NodeCache cache)

  Get the keys for all of the nodes (other than the `primary parent`) under which this node appears.

  Parameters:

  Returns:
    the immutable set of keys to the additional parents, excluding the primary parent

### getPrimaryType

    Name getPrimaryType(NodeCache cache)

  Get the primary type for this node.

  Parameters:

  Returns:
    the property iterator; never null but possibly empty

### getChildReferences

    ChildReferences getChildReferences(NodeCache cache)

  Get the set of child references for this node. Note that each child reference will need to be resolved by the caller.

  Parameters:
