        `name` - the name for the node
        `snsIndex` - the same-name-sibling index; must be positive
        `context` - the context in which the child should be evaluated; may be null if there is no context
      Returns:
        the child reference, or null if there is no such child

    - #### getChild

          public ChildReference getChild(NodeKey key,
                                ChildReferences.Context context)

      Description copied from interface: `ChildReferences`
      Look for the child reference that has the node key.
      Parameters:
        `key` - the node key of the child
        `context` - the context in which the child should be evaluated; may be null if there is no context
      Returns:
        the child reference, or null if there is no such child

    - #### getChild

      Returns:
        the child reference, or null if there is no such child

    - #### hasChild

          public boolean hasChild(NodeKey key)

      Specified by:
        `iterator` in interface `ChildReferences`
      Overrides:
        `iterator` in class `AbstractChildReferences`
      Returns:
        the iterator; never null

    - #### iterator

          public Iterator<ChildReference> iterator(Name name,

      Description copied from interface: `ChildReferences`
      Get an iterator over all of the children that have same name matching the supplied value. This essentially returns an iterator over all of the same-name-siblings.
      Specified by:
        `iterator` in interface `ChildReferences`
      Overrides:
        `iterator` in class `AbstractChildReferences`
      Parameters:
        `name` - the name of the same-name-sibling nodes; may not be null
        `context` - the context in which the child should be evaluated; may be null if there is no context

    - #### iterator

          public Iterator<ChildReference> iterator(ChildReferences.Context context)

      Description copied from class: `AbstractChildReferences`
      Get an iterator over all child references in this collection, but base the SNS indexes upon those already consumed.
