atobjs

Atobjs, short for "atomic objects," are a concept in computer science and software engineering that refer to data structures or objects that are indivisible and immutable. This means that once an atobj is created, its state cannot be changed. Instead of modifying an existing atobj, a new atobj is created with the desired changes. This immutability provides several benefits, including thread safety, easier reasoning about code, and simplified debugging.

Atobjs are commonly used in functional programming languages, where immutability is a core principle. However, they can also be beneficial in other paradigms. For example, in concurrent programming, atobjs can help avoid race conditions and ensure data consistency across multiple threads.

The concept of atobjs is closely related to value semantics, where the identity of an object is determined by its value rather than its reference. This is in contrast to reference semantics, where two objects are considered equal if they reference the same memory location.

In practice, atobjs can be implemented using various data structures, such as tuples, lists, or custom classes. The key characteristic is that they do not provide any methods to modify their state once created. Instead, they offer methods to create new atobjs with the desired changes.

While atobjs offer many advantages, they also have some limitations. For example, they can lead to increased memory usage, as new objects are created rather than modified in place. Additionally, they may not be suitable for all types of data or use cases. Therefore, it is important to carefully consider the trade-offs when deciding whether to use atobjs in a particular context.
