FirebaseQueryBridge

public final class FirebaseQueryBridge

An implementation of QueryBridge based on the Firebase Realtime Database.

This bridge stores the QueryResponse data to a location in a given Firebase database and retrieves the database path to that response as the result.

More formally, for each encountered Query, the bridge performs a call to the QueryService and stores the resulting entity states into the given database. The data is stored as a list of strings. Each entry is a JSON representation of an entity state. The path produced by the bridge as a result is the path to the database node containing all those records. The absolute position of such a node is not specified, thus the result path is the only way to read the data from the database.
