Appendix B. Generic data access in statically-typed languages
Representing data with generic data structures fits naturally in dynamically-typed programming languages like JavaScript, Ruby, or Python. However, in statically-typed programming languages like Java or C#, representing data as string maps with values of an unspecified type is not natural for several reasons:
-
Accessing map fields requires a type cast.
-
Map field names are not validated at compile time.
-
Autocompletion and other convenient IDE features are not available.
This appendix explores various ways to improve access to generic data in statically-typed languages. We’ll look at:
-
Value getters for maps to avoid type casting when accessing map fields
-
Typed getters for ...
