the class ContentFragmentUtils method getComponentExporters.

/**
 * Gets a map of all resources with the resource name as the key and the corresponding {@link ComponentExporter}
 * model as the value.
 *
 * The returned map is ordered as provided by the resourceIterator.
 * Any resource that cannot be adapted to a {@link ComponentExporter} model is omitted from the returned map.
 *
 * @param resourceIterator Iterator of resources for which to get the component exporters.
 * @param modelFactory Model factory service.
 * @param slingHttpServletRequest Current request.
 * @param callerResource The page or template resource that references the experience fragment or content fragment.
 * @return Ordered map of resource names to {@link ComponentExporter} models.
