  - ### Method Detail

    - #### getCollection

          protected java.util.Collection<Resource> getCollection()

      Sort the contained elements.
      Specified by:
        `getCollection` in class `BaseResourceCollectionWrapper`
      Returns:
        a Collection of Resources.

    - #### add

          public void add​(ResourceComparator c)

      Add a ResourceComparator to this Sort ResourceCollection. If multiple ResourceComparators are added, they will be processed in LIFO order.
      Parameters:
        `c` - the ResourceComparator to add.

    - #### dieOnCircularReference

          protected void dieOnCircularReference​(java.util.Stack<java.lang.Object> stk,
                                                Project p)
                                         throws BuildException

      Overrides the BaseResourceCollectionContainer version to recurse on nested ResourceComparators.
      Overrides:
        `dieOnCircularReference` in class `AbstractResourceCollectionWrapper`
      Parameters:
        `stk` - the stack of data types to use (recursively).
        `p` - the project to use to dereference the references.
      Throws:
        `BuildException` - on error.
