C

ChildEventListener Classes implementing this interface can be used to receive events about changes in the child locations of a given DatabaseReference ref.

D

DatabaseError	Instances of DatabaseError are passed to callbacks when an operation failed.
DatabaseException	This error is thrown when the Firebase Database library is unable to operate on the input it has been given.
DatabaseReference	A Firebase reference represents a particular location in your Database and can be used for reading or writing data to that Database location.
DatabaseReference.CompletionListener	This interface is used as a method of being notified when an operation has been acknowledged by the Database servers and can be considered complete
DataSnapshot	A DataSnapshot instance contains data from a Firebase Database location.

E

Exclude Marks a field as excluded from the Database.

F

FirebaseDatabase The entry point for accessing a Firebase Database.

G

GenericTypeIndicator<T> Due to the way that Java implements generics (type-erasure), it is necessary to use a slightly more complicated method to properly resolve types for generic collections at runtime.

I

IgnoreExtraProperties Properties that don't map to class fields are ignored when serializing to a class annotated with this annotation.

L

Logger	This interface is used to setup logging for Realtime Database.
Logger.Level	The log levels used by the Realtime Database library

M

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

O

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

P

PropertyName Marks a field to be renamed when serialized.

Q

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

S

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

T

ThrowOnExtraProperties	Properties that don't map to class fields when serializing to a class annotated with this annotation cause an exception to be thrown.
Transaction	The Transaction class encapsulates the functionality needed to perform a transaction on the data at a location.
Transaction.Handler	An object implementing this interface is used to run a transaction, and will be notified of the results of the transaction.
Transaction.Result	Instances of this class represent the desired outcome of a single run of a `Transaction.Handler`'s doTransaction method.

V

ValueEventListener Classes implementing this interface can be used to receive events about data changes at a location.
