DataSnapshot

A DataSnapshot instance contains data from a Firebase Database location. Any time you read Database data, you receive the data as a DataSnapshot.

They are efficiently-generated immutable copies of the data at a Firebase Database location. They can't be modified and will never change. To modify data at a location, use a
DatabaseReference reference (e.g. with DatabaseReference.setValue).
