  2. Immutable object - Wikipedia

    en.wikipedia.org/wiki/Immutable_object

    In Java [5]: 84 these are StringBuffer and StringBuilder (mutable versions of Java String) and in .NET this is StringBuilder (mutable version of .Net String). Python 3 has a mutable string (bytes) variant, named bytearray. [6] Additionally, all of the primitive wrapper classes in Java are immutable.

  3. Flyweight pattern - Wikipedia

    en.wikipedia.org/wiki/Flyweight_pattern

    One example is mutability: whether the objects storing extrinsic flyweight state can change. Immutable objects are easily shared, but require creating new extrinsic objects whenever a change in state occurs. In contrast, mutable objects can share state. Mutability allows better object reuse via the caching and re-initialization of old, unused ...

  4. Mutation testing - Wikipedia

    en.wikipedia.org/wiki/Mutation_testing

    Given that mutations depend on these operators, scholars have created a collection of mutation operators to accommodate different programming languages, like Java. The effectiveness of these mutation operators plays a pivotal role in mutation testing.

  5. Persistent data structure - Wikipedia

    en.wikipedia.org/wiki/Persistent_data_structure

    In computing, a persistent data structure or not ephemeral data structure is a data structure that always preserves the previous version of itself when it is modified. Such data structures are effectively immutable, as their operations do not (visibly) update the structure in-place, but instead always yield a new updated structure.

  6. Language interoperability - Wikipedia

    en.wikipedia.org/wiki/Language_interoperability

    Mutability becomes an issue when trying to create interoperability between pure functional and procedural languages. Languages like Haskell have no mutable types, whereas C++ does not provide such rigorous guarantees. Many functional types when bridged to object oriented languages can not guarantee that the underlying objects won't be modified.

  8. Mutability - Wikipedia

    en.wikipedia.org/wiki/Mutability

    The principle of mutability is the notion that any physical property which appears to follow a conservation law may undergo some physical process that violates its conservation. [ 1 ] [ 2 ] [ 3 ] John Archibald Wheeler offered this speculative principle after Stephen Hawking predicted the evaporation of black holes which violates baryon number ...
