/**
* Extension to {@link MockMaker} for mock makers that changes inline method implementations
* and need keep track of created mock objects.
*
* Mockito's default inline mock maker keeps track of created mock objects via weak reference map.
* This poses a risk of memory leaks in certain scenarios
* (issue #1619).
* There is no clean way to tackle those problems at the moment.
* Hence, {@code InlineMockMaker} interface exposes methods to explicitly clear mock references.
* Those methods are called by {@link MockitoFramework#clearInlineMocks()}.
* When the user encounters a leak, he can mitigate the problem with {@link MockitoFramework#clearInlineMocks()}.
*
* {@code InlineMockMaker} is for expert users and framework integrators, when custom inline mock maker is in use.
* If you have a custom {@link MockMaker} that keeps track of mock objects,
* please have your mock maker implement {@code InlineMockMaker} interface.
* This way, it can participate in {@link MockitoFramework#clearInlineMocks()} API.
*
* @since 2.25.0
