When a program initializes, the mutator allocates memory space for new small objects in the nursery. The nursery serves as a buffer to maintain recently created objects. If these objects remain alive during the garbage collection cycle, they may undergo aging and be promoted to Generation 0 for small objects or Generation 1 for large objects. So, the nursery, Gen 0, and Gen 1 are pipelining with each other and interacting accordingly. I want to explain my understanding as follow:
-
Nursery:
- Newly allocated objects start in the nursery, designed for short-lived objects.
-
Garbage Collection Cycle:
- The garbage collector examines nursery objects during a cycle.
- Surviving objects in the nursery may age within the same generation (e.g., Gen 0).
-
Generational Promotion:
- Objects surviving multiple cycles may be promoted to the next older generation (e.g., from Gen 0 to Gen 1).
-
Interaction and Pipeline:
- Objects move through a pipeline-like structure: nursery to Gen 0, and potentially to Gen 1.
- The nursery buffers short-lived objects, Gen 0 represents the initial stage for object promotion, and Gen 1 (and further generations) accommodates objects with longer lifetimes.
Is my understanding correct?
I expect the some helpful explanations.
