class XyzMissingTargetAlter

This class contains attributes to reorder or remove alter implementations.

The idea behind the hook names:

  • hook_test_ab_alter() has implementations in modules A and B.
  • hook_test_b_alter() has implementations only in module B. As a consequence, it has no implementations if module B is not installed.
