 /**
  * Provides most of the functionality specific to a Runner that implements a
  * "parent node" in the test tree, with children defined by objects of some data
- * type {@code T}. (For {@link BlockJUnit4ClassRunner}, {@code T} is
- * {@link Method} . For {@link Suite}, {@code T} is {@link Class}.) Subclasses
- * must implement finding the children of the node, describing each child, and
- * running each child. ParentRunner will filter and sort children, handle
+ * type {@code T}.
