AtomicInteger0

AtomicInteger0 is not a standard, widely defined type in major programming languages. In practice, the name is sometimes used in codebases as a convention to denote an atomic integer value that starts at zero, or as a wrapper class intended to provide atomic operations around an integer with an initial value of zero. Because it is not part of a formal language specification, the exact API and behavior of AtomicInteger0 can vary by project.

Overview and purpose

An AtomicInteger0 typically aims to enable thread-safe access and modification of an integer without explicit synchronization. It relies on atomic primitives to prevent data races when multiple threads read or update the value concurrently. The core goal is to offer predictable, lock-free or low-lock operations suitable for counters, sequence numbers, or simple flags used in concurrent algorithms.

Common operations

Where implemented, AtomicInteger0-like types provide operations such as: getting the current value, setting a new value, compare-and-set (CAS) semantics, and arithmetic updates such as incrementing, decrementing, or adding a delta. The exact method names and availability (for example, getAndIncrement, incrementAndGet, or weak variants) depend on the library or language.

Implementation notes

Such a type would typically be built on atomic primitives provided by the platform (for example, CAS instructions). In Java, the standard AtomicInteger serves this role, while AtomicInteger0 would be a non-standard alias or wrapper in a specific codebase. The emphasis is on correctness under concurrency, with attention to memory visibility guarantees.

Use and portability

Because AtomicInteger0 is not a universal standard, its use and behavior should be documented in the project’s API. When portability across languages is required, consider the language’s official atomic facilities (for example, Java’s AtomicInteger, C++ std::atomic, or C#’s Interlocked).
