    `values` - Attribute values to overide in the clone.
  Returns:
    A clone of this resource.

### getKey

    public java.lang.Integer getKey()

  Get the container Key. This key must be unique and unchanged during the container life.
  Returns:
    a String instance.

### getSpaceEntry

    protected SpaceEntry getSpaceEntry()

  Description copied from class: Resource
  Get the space entry for that resource. This Object is use to retrieve the resource in the resource space.
  Overrides:
    getSpaceEntry in class Resource
  Tags copied from class: Resource
  Returns:
    A spaceEntry instance.

### getChildrenSpaceEntry

    protected SpaceEntry getChildrenSpaceEntry()

  Get the SpaceEntry of our children resources.
  Returns:
    A SpaceEntry instance.

### resourceModified

    public void resourceModified(StructureChangedEvent evt)

  This handles the `RESOURCE_MODIFIED` kind of events.
  Overrides:
    resourceModified in class AbstractContainer
  Parameters:
    `evt` - The StructureChangeEvent.

### resourceCreated

    public void resourceCreated(StructureChangedEvent evt)

  A new resource has been created in some space. This handles the `RESOURCE_CREATED` kind of events.
  Overrides:
    resourceCreated in class AbstractContainer
  Parameters:
    `evt` - The event describing the change.

### resourceRemoved

  A resource is about to be removed This handles the `RESOURCE_REMOVED` kind of events.
  Overrides:
    resourceRemoved in class AbstractContainer
  Parameters:
    `evt` - The event describing the change.

### updateDefaultChildAttributes

    protected ResourceContext updateDefaultChildAttributes(java.util.Hashtable attrs)

  Update default child attributes. A parent can often pass default attribute values to its children, such as a pointer to itself (the parent attribute).

  This is the method to overide when you want your container to provide these kinds of attributes. By default this method will set the following attributes:

  name
    The name of the child (it's identifier) - String instance.
  parent
    The parent of the child (ie ourself here) - a ContainerResource instance.
  url
    If a identifier attribute is defined, that attribute is set to the full URL path of the children.
  Overrides:
    updateDefaultChildAttributes in class AbstractContainer
  Tags copied from class: AbstractContainer
  Parameters:
    `attrs` - A hashtable.

### enumerateResourceIdentifiers

    public java.util.Enumeration enumerateResourceIdentifiers(boolean all)

  Enumerate children resource identifiers.
  Overrides:
    enumerateResourceIdentifiers in class AbstractContainer
  Parameters:
    `all` - Should all resources be enumerated ? Resources are often created on demand only, this flag allows the caller to tell the container about wether it is interested only in already created resources, or in all resources (even the one that have not yet been created).
  Returns:
    An String enumeration, one element per child.

### createDefaultResource

    public ResourceReference createDefaultResource(java.lang.String name)

  Create a default child resource in that container. This method is called by the editor to add a default resource in the container under the given name. The meaning of default is left up to the container here.
  Overrides:
    createDefaultResource in class AbstractContainer
  Parameters:
    `name` - The identifier for the new resource.

### getMatchingCharsCount

    protected int getMatchingCharsCount(java.lang.String s1,
                                        java.lang.String s2)

  Get the number of matching character (case sensitive). ex getMatchingCharsCount("index.html", "Index.html") = 10.
  Parameters:
    `s1` - the first string.
    `s2` - the second string.
  Returns:
    -1 if s1 and s2 are not equals (ignoring case), otherwise the number of matching character (case sensitive).
