fetchEntityRel
fetchEntityRel is a function used in software development, likely within a specific framework or library. Its primary purpose is to retrieve related entities based on a given entity and a specified relationship. When invoked, fetchEntityRel takes an identifier for the primary entity and the name or type of the relationship as input. It then queries the underlying data store or system to find all entities that are linked to the initial entity through that particular relationship. The output of the function is typically a collection of these related entities. This mechanism is crucial for building complex data structures and navigating relationships between different pieces of information within an application. For example, in a social networking application, fetchEntityRel could be used to retrieve all of a user's friends (the related entities) given the user's ID (the primary entity) and the 'friends' relationship. The specific implementation and available parameters for fetchEntityRel would depend on the context of the software it belongs to.
