Naming convention

Java naming convention

Getters and setters

• Getters (get, is)
  • Takes no parameters
  • Does not alter the object in any way; it is constant
  • Can be called multiple times, and in any order
  • Returns a consistent single result

• Setters (set)
  • Takes one parameter
  • May or may not alter the object
  • Only affects the object that has the setter; it does not persist anywhere else
  • Can be called multiple times, and in any order

Finders & filters

• Finders (find)
  • Takes zero or more arguments (which act as filter or sorting controls)
  • Does not alter the object in any way; it is constant
  • Can be called multiple times, and in any order
  • Returns a consistent, single, non-null collection result

Factories

• Factories
  • Responsible for creating objects - not persisting them!

• Factory classes
  • Conform to [ObjectType]Factory naming convention

• Factory methods
  • Conform to create[ObjectType] naming convention

Persistance

• Repositories
  • Conform to [ObjectType]Repository naming convention
  • Methods such as save*, load*, find*, read*, write*, delete*
