Type SafeList<T>
Namespace ImageResizer.Collections
Interfaces IEnumerable<T>
SafeList is mutable, but it uses immutable data structures to minimize the need for locking.
The provided manipulation
Exposes a immutable list. Changes are made by copying the lists.
SafeList is
Never perform logic on SafeList directly, always use GetList() or GetCollection() first, followed by SetList().
If you need involved list-fu, use ModifyList and specify a callback. It will execute inside a lock, preventing changes on other threads from overwriting each other.
