getDoorState

getDoorState is a function or method used in software systems to query the current condition of a door within a device, building automation, or robotic platform. It returns a representation of whether the door is physically open, closed, or in transit, and may also reflect security status such as locked or unlocked.

Common return values are defined as a DoorState enumeration such as OPEN, CLOSED, AJAR, LOCKED, UNLOCKED, and UNKNOWN. Some implementations include transitional states like OPENING and CLOSING to indicate movement in progress, and a JAMMED or ERROR state for sensor failure or obstruction. The exact set of states depends on the system's design and the sensor hardware.

In many systems, getDoorState accepts an identifier to specify which door to query, for example a doorId or doorHandle, allowing multiple doors to be managed within a single interface. The function may retrieve its result from a physical sensor, a software model, or a combination of both, and may reflect either a local sensor or a remote device.

Usage characteristics vary: some implementations return a synchronous value, others are asynchronous and yield a promise or future. If the sensor is unavailable or data cannot be determined, getDoorState may return UNKNOWN or raise an exception. Some designs attach a timestamp or confidence score to the returned state to aid decision making.

Example: state = getDoorState(doorId); if state == OPEN then triggerNotification(); else if state == CLOSED then proceed;
