Referentievergelijking is a term used in computer science to describe the comparison of whether two references point to the same object instance rather than comparing the objects’ contents. The concept is especially relevant for object‑oriented languages in which objects exist on the heap and are accessed through reference types. When two reference variables are compared using referentievergelijking, the outcome is true only if both variables reference the very same memory location.
In many programming languages the operator or keyword for referentievergelijking is a double equals sign (==), a
The distinction matters in scenarios like caching, singleton patterns, and identity mapping, where the identity of
