UnsafeWeakList (Unofficial IntelliJ Community Edition API docs)

java.lang.Object
- java.util.AbstractCollection<T>
- - com.intellij.util.containers.UnsafeWeakList<T>

All Implemented Interfaces:

java.lang.Iterable<T>, java.util.Collection<T>

Direct Known Subclasses:

WeakList
```
public class UnsafeWeakList<T>
extends java.util.AbstractCollection<T>
```
Implementation of the Collection interface which:
- Stores elements using weak semantics (see WeakReference)
- Automatically reclaims storage for garbage collected elements
- Is NOT thread safe
- Is NOT RandomAccess, because garbage collector can remove element at any time
- Does NOT support null elements
Please note that since weak references can be collected at any time, index-based methods (like get(index)) or size-based methods (like size()) are dangerous, misleading, error-inducing and are not supported. Instead, please use #add(T) and iterator().
