  --- | --- | ---
  `static HierarchyListener` | AWTEventMulticaster.`add​(HierarchyListener a, HierarchyListener b)` | Adds hierarchy-listener-a with hierarchy-listener-b and returns the resulting multicast listener.
  `HierarchyListener[]` | Component.`getHierarchyListeners()` | Returns an array of all the hierarchy listeners registered on this component.
  `static HierarchyListener` | AWTEventMulticaster.`remove​(HierarchyListener l, HierarchyListener oldl)` | Removes the old hierarchy-listener from hierarchy-listener-l and returns the resulting multicast listener.

  Methods in java.awt with parameters of type HierarchyListener
  Modifier and Type | Method | Description
  --- | --- | ---
  `static HierarchyListener` | AWTEventMulticaster.`add​(HierarchyListener a, HierarchyListener b)` | Adds hierarchy-listener-a with hierarchy-listener-b and returns the resulting multicast listener.
  `void` | Component.`addHierarchyListener​(HierarchyListener l)` | Adds the specified hierarchy listener to receive hierarchy changed events from this component when the hierarchy to which this container belongs changes.
  `static HierarchyListener` | AWTEventMulticaster.`remove​(HierarchyListener l, HierarchyListener oldl)` | Removes the old hierarchy-listener from hierarchy-listener-l and returns the resulting multicast listener.
  `void` | Component.`removeHierarchyListener​(HierarchyListener l)` | Removes the specified hierarchy listener so that it no longer receives hierarchy changed events from this component.
