    - #### ReorderChildrenComponentChange

          public ReorderChildrenComponentChange(List<String> childIds)

      Constructs a ReorderChange with the given List of identifiers for children.
      Parameters:
        `childIds` - An in-order collection (List) of Ids (as java.lang.String) of child components. This List implementation should be of type java.io.Serializable in order to be persisted. If no identifier was passed, it would be assumed that the list consists of the Ids.
      Throws:
        `IllegalArgumentException` - if supplied childIds were to be null.

    - #### ReorderChildrenComponentChange

          public ReorderChildrenComponentChange(List<String> childIds,
                                        String identifier)

      Constructs a ReorderChange with the given List of identifiers for children.
      Parameters:
        `childIds` - An in-order collection (List) of Ids (as java.lang.String) of child components. This List implementation should be of type java.io.Serializable in order to be persisted.
        `identifier` - Determines the type of identifiers which the List consists of.
      Throws:
        `IllegalArgumentException` - if supplied childIds were to be null or supplied identifier was to be null or emtpy string.

  - ### Method Detail

    - #### getChildIds

          public List<String> getChildIds()

      Returns an unmodifiable List of the identifiers for the children.

    - #### getIdentifier

          public final String getIdentifier()

      Returns the identifier type.

    - #### changeComponent

          public void changeComponent(javax.faces.component.UIComponent uiComponent)

      Apply this change to the specied component In case children were to be removed between the time when this Change was added, and the time when it was applied, maybe due to application of a RemoveChildrenChange, such children are not re-instated. In case children were to be added between the time when this Change was added, and the time when it was applied, maybe due to application of an AddChildChange, such children are appended to the end of the list in preserving the order in which they were added (that is they appear at the end).
      Specified by:
        `changeComponent` in class `ComponentChange`
      Parameters:
        `uiComponent` - the UIComponent to apply the change to

    - #### changeDocument

          public void changeDocument(Node componentNode)

      Apply this change to the specied root DOM Node of the component In case children were to be removed between the time when this Change was added, and the time when it was applied, maybe due to application of a RemoveChildrenChange, such children are not re-instated. In case children were to be added between the time when this Change was added, and the time when it was applied, maybe due to application of an AddChildChange, such children are appended to the end of the list in preserving the order in which they were added (that is they appear at the end).
      Specified by:
        `changeDocument` in interface `DocumentChange`
      Parameters:
        `componentNode` - DOM node of the component to apply the change to
