In the Java language, a single-implementation-inheritance model allows you to extend base classes and add new methods and fields, and so on.

It's also important for creating abstract base classes and interfaces whose derived classes or implementations may need to throw exceptions.

Since generic classes can serve as base classes, the same design considerations apply here as with non-generic classes.

However, some filters require a copy operation; this requirement influences the choice of base classes.

Which are abstract base classes that can be extended to create collection classes that are strongly typed.

Determine which base classes to use and derive the filter class (and pin classes, if necessary) from the base classes.

To do so, developers would need to manually implement the provided interfaces and extend the abstract base classes.

They are not documented separately from their base classes, because their behavior is described by the base class documentation.

In addition, someone could inherit from these classes, even though you never intended these classes to serve as base classes.

Classes derived from base classes that contain MustOverride members must either override such members or use the MustInherit modifier.

The @MappedSuperclass annotation lets you use mappings defined in base classes.

So instead of showing you an example script, I'm just going to cut to the chase and talk about Products and base classes.

There are no base classes to extend from, the classes are concrete (not abstract), and there's no XML file.

Before I conclude the discussion of the sizing of types, I also want to mention base classes.
