Instances of this class encapsulate the data and priority at a location.

The OnDisconnect class is used to manage operations that will be run on the server when this client disconnects.

The Query class (and its subclass, DatabaseReference) are used for reading data.

Contains placeholder values to use when writing data to the Firebase Database.

The Transaction class encapsulates the functionality needed to perform a transaction on the data at a location.

Instances of this class represent the desired outcome of a single run of a Handler's doTransaction method.
