Union types are used in several languages, notably C-language, to contain several different types which can "overlap" in the same memory space. In other words, they might contain different fields all of which start at the same memory offset, even when they might have different lengths an...

The Prototype pattern is a creational pattern that creates new objects by cloning existing prototype object. The prototype pattern speeds up the instantiation of classes when copying objects is faster. The prototype pattern is a creational design pattern. It is used when the type of objects to...

Java Atomic Types are simple mutable types that provide basic operations that are thread-safe and atomic without resorting to locking. They are intended for use in cases where locking would be a concurrency bottleneck, or where there is risk of deadlock or livelock. ParameterDescriptionsetVola...

A type-safe builder is a concept, rather than a language feature, so it is not strictly formalized. A typical structure of a type-safe builder A single builder function usually consists of 3 steps: Create an object. Execute lambda to initialize the object. Add the object to structure or r...

Type instability occurs when a variable's type can change at runtime, and hence cannot be inferred at compile-time. Type instability often causes performance problems, so being able to write and identify type-stable code is important.

Prior VHDL 1993, two concurrent processes could communicate only with signals. Thanks to the simulation semantics of the language that updates signals only between simulation steps, the result of a simulation was deterministic: it did not depend on the order chosen by the simulation scheduler to e...

s is an instance of ^a you want to accept at compile-time, which can be anything that implements the members you actually call using the syntax. ^a is similar to generics which would be 'a (or 'A or 'T for example) but these are compile-time resolved, and allow for anything that fits all the requ...
