bindingstype

Bindingstype is a conceptual category used to classify mechanisms by which names, identifiers, or data values are bound to meanings in software systems. The term appears in some technical writings as a way to discuss how and when bindings are established, and what rules govern them. It is not a universally standardized term, but it provides a framework for comparing binding strategies across domains such as programming languages and user interface frameworks.

Timing of binding: static (compile-time) binding resolves identifiers once during compilation, while dynamic (runtime) binding resolves them during program execution. Early binding and late binding are terms often used to describe the same distinction in older literature, with early binding implying more fixed bindings and late binding enabling more flexibility.

Direction and interaction: one-way binding propagates changes from a source to a dependent target, while two-way binding allows changes in either direction. Event binding connects program logic to user or system events without directly binding values. In language theory, binding also concerns how variable names are associated with memory locations or values via lexical scope or dynamic scope.

Applications and examples: in compilers, static vs dynamic binding appears in function dispatch (static calls vs virtual calls) and in symbol resolution. In modern UI frameworks, data binding types describe how model data is synchronized with views, with two-way binding common in MVVM toolkits and one-way binding used where data flow is unidirectional.
