DynamicEntity class final
A GeoElement that represents a real-world object received from a DynamicEntityDataSource.
Dynamic entities are updated with data coming from a stream. These updates are referred to as observations and are represented by the DynamicEntityObservation class. An observation is a static snapshot of the state of a dynamic entity at a given time. This snapshot includes the associated dynamic entity's location (geometry) as well as all its attributes. For example, an observation for a moving aircraft may include updates to attributes like speed, altitude, and heading in addition to its updated location. While observations remain static, a dynamic entity changes because it's essentially a pointer to the most recent observation.
The properties of a DynamicEntity, such as its attributes and geometry, are updated when new observations are received from the server. You should not cache the DynamicEntity.geometry or DynamicEntity.attributes collection properties as they are completely replaced when a new observation is received for the associated DynamicEntity.
