Interface CodeLookup<S>

All Known Subinterfaces:

Language

public interface CodeLookup<S>

CodeLookup is an interface to facilitate finding elements in small sets of enumerated Objects, usually a java Enum.

getCode returns a value that can be used to retrieve the Object. The actual lookup is not part of this interface, because it will be in most cases implemented by either a static method or a service.

In order for this interface to be of use, getCode must return unique codes across all instances of a given implementation, so when

  class Foo implements CodeLookup<Integer>
 

then if

     foo1.getCode().equals(foo2.getCode())
 

is true, so should.

     foo1.equals(foo2)
 

Typical usecases are web requests or database persistence.
