Dgetname

Dgetname is a software utility function described in software design literature as a means to retrieve a user-facing display name for a given entity. It is designed for applications that present names in user interfaces while handling localization and privacy considerations. In typical usage, dgetname takes an identifier for a person, account, or device and an optional configuration object, returning a string suitable for display in the UI.

Common behavior includes a prioritized resolution order. The function first attempts to use a primary displayName field from the identity source; if that is not available, it constructs a name from givenName and familyName or, failing those, falls back to a username or email prefix. If a locale is supplied, the output is adapted to locale conventions, including case and script rules where applicable. The function may also apply privacy or policy overrides, returning redacted forms or initials when display is restricted by user preferences or role.

Dgetname is often designed to be fast, with caching for the current session and optionally per-tenant configuration in multi-tenant systems. It is typically stateless from the caller’s perspective, relying on a centralized identity provider or directory service.

Example usage: dgetname(userId); // "Alice Chen" dgetname(userId, { locale: "fr-FR" }); // "Alice Chen" dgetname(userId, { privacy: true }); // "A. C."
