Marks the class as a Data Access Object.
Data Access Objects are the main classes where you define your database interactions. They can include a variety of query methods.
The class marked with @Dao
should either be an interface or an abstract class. At compile
time, Room will generate an implementation of this class when it is referenced by a
Database
.
An abstract @Dao
class can optionally have a constructor that takes a Database
as its only parameter.
It is recommended to have multiple Dao
classes in your codebase depending on the tables
they touch.
