    - #### walk

          public void walk(javax.faces.context.FacesContext context,
                  DataVisitor visitor,
                  Range range,
                  Object argument)

      Description copied from class: `ExtendedDataModel`
      Iterate over model by "visitor" pattern, for given range
      Specified by:
        `walk` in class `ExtendedDataModel<E>`
      Parameters:
        `context` - current JSF context.
        `visitor` - instance of `DataVisitor`, for process each row.
        `range` - Implementation-specific range of data keys.
        `argument` - Implementation-specific argument

    - #### getRowKey

          public Object getRowKey()

      Specified by:
        `getRowKey` in class `ExtendedDataModel<E>`
      Returns:
        key for selected data or `null`

    - #### setRowKey

          public void setRowKey(Object key)

      Description copied from class: `ExtendedDataModel`

      Instead of simple `int` for current state selection, this model can use any object for select current data. Implementation depend on model, with any restrictions :

      1. key must be `Serializable`.
      2. `Object.toString()` method must return representation compatible with `UIComponent.getClientId(javax.faces.context.FacesContext)`, as far as this string will be appended to clientId of iterator component.
      Specified by:
        `setRowKey` in class `ExtendedDataModel<E>`
      Parameters:
        `key` - key for select current data, or null for clear selection.

    - #### getRowCount

          public int getRowCount()

    - #### getRowIndex

          public int getRowIndex()

      Specified by:
        `getRowIndex` in class `javax.faces.model.DataModel<E>`

    - #### getWrappedData
