-/**
- * Equivalent to {@link ExtensionRegistry} but supports only "lite" types.
- * <p>
- * If all of your types are lite types, then you only need to use
- * {@code ExtensionRegistryLite}.  Similarly, if all your types are regular
- * types, then you only need {@link ExtensionRegistry}.  Typically it does not
- * make sense to mix the two, since if you have any regular types in your
- * program, you then require the full runtime and lose all the benefits of
- * the lite runtime, so you might as well make all your types be regular types.
- * However, in some cases (e.g. when depending on multiple third-party libraries
- * where one uses lite types and one uses regular), you may find yourself
- * wanting to mix the two.  In this case things get more complicated.
- * <p>
- * There are three factors to consider:  Whether the type being extended is
- * lite, whether the embedded type (in the case of a message-typed extension)
- * is lite, and whether the extension itself is lite.  Since all three are
- * declared in different files, they could all be different.  Here are all
- * the combinations and which type of registry to use:
- * <pre>
- *   Extended type     Inner type    Extension         Use registry
- *   =======================================================================
- *   lite              lite          lite              ExtensionRegistryLite
- *   lite              regular       lite              ExtensionRegistry
- *   regular           regular       regular           ExtensionRegistry
- *   all other combinations                            not supported
- * </pre>
- * <p>
- * Note that just as regular types are not allowed to contain lite-type fields,
- * they are also not allowed to contain lite-type extensions.  This is because
- * regular types must be fully accessible via reflection, which in turn means
- * that all the inner messages must also support reflection.  On the other hand,
- * since regular types implement the entire lite interface, there is no problem
- * with embedding regular types inside lite types.
