getInterfaceObject

getInterfaceObject is a function used in software systems to obtain an object that implements a specified interface. It is commonly employed in frameworks that support dynamic component discovery, plugin architectures, or cross-system communication. The function takes a descriptor that identifies the desired interface, such as a name, type, or interface identifier, and returns an object that conforms to that interface.

In practice, getInterfaceObject may perform several forms of resolution: constructing a new instance that implements the interface, returning a cached singleton, wrapping a proxy to a remote or asynchronous object, or delegating to a service locator or dependency injection container. The exact behavior depends on the environment and configuration. If no matching implementation is available, the function may throw an error, return null, or signal failure through a result object.

Typical usage patterns include plug-in systems where components advertise the interfaces they implement, modular applications that load features on demand, and inter-process or networked communications where remote interfaces are exposed locally. A caller can then interact with the returned object through the interface’s methods without needing knowledge of the underlying implementation.

Example: obj = getInterfaceObject('ILogger'); obj.log('start'); In statically typed languages, the returned value is bound to the interface type; in dynamic languages it may be treated as any. Considerations include type safety, lifecycle management, caching, error handling, and security.
