Class ObjectCache.Entry

java.lang.Object

fabric.worker.ObjectCache.Entry

Enclosing class:

ObjectCache

public static final class ObjectCache.Entry
extends java.lang.Object

Entries hold either an _Impl or a SerializedObject (but not both). This class is thread safe.

Possible states:

1. overridden: next is non-null, impl and serialized are null (the entry in next should be used instead of this)
   • This is done because we maintain the invariant that exactly one Entry object is associated with any given _Impl or SerializedObject.
2. serialized: impl and next are null, serialized and store are non-null
3. deserialized: serialized and next are null, impl is non-null
4. evicted: impl, serialized, and next are null
