+ * Abstract Objectify translator for {@link ImmutableSortedMap} fields.
+ *
+ * <p>This class should be extended for each set of concrete key/value types you wish to support.
+ * This translator will only apply to {@code ImmutableSortedMap} model fields that have precicely
+ * the same type parameters you specified.
+ *
+ * <p>This translator serves a similar purpose to
+ * {@link com.googlecode.objectify.impl.translate.MapifyTranslatorFactory @Mapify}. Except this
+ * maintains perfect immutability of the field value. Subclasses may override the
+ * {@link #transformBeforeSave(ImmutableSortedMap)} methods to perform mutation on a per-concrete
+ * type basis. This abstraction is also more readable than {@code @Mapify} because it shifts the
+ * boilerplate into translator magic, rather than convoluting model data structures.
+ *
+ * <h3>Entity Data Layout</h3>
+ *
+ * <p>For example, if you had an {@code ImmutableSortedMap<String, String>} on a field named
+ * {@code field}, then this would look like:<pre>   {@code
+ *
+ *   field.key -> [key1, key2]
+ *   field.value -> [value1, value2]}</pre>
+ *
+ * <p>If you had an {@code ImmutableSortedMap<String, EmbeddedClass>} on a field named
+ * {@code field}, where {@code EmbeddedClass} defines two {@code foo} and {@code bar} fields, then
+ * the embedded properties might look like:<pre>   {@code
+ *
+ *   field.key -> [key1, key2]
+ *   field.value.foo -> [foo1, foo2]
+ *   field.value.bar -> [bar1, bar2]}</pre>
