+ <h2>Cache API.</h2>
+ <p>
+ The Cache API/SPI is an extension point for Entity Store caching.
+ </p>
+ <p>
+ The API part is only to allow caching options to be passed to the underlying extension in a uniform and
+ standard way. CacheOptions are to be passed as meta info on the optional Cache extension that is specified
+ during assembly phase. Example;
+ </p>
+<pre><code>
+public void assemble( ModuleAssembly module )
+{
+ CacheOptions options = new CacheOptions( true, true, false );
+ module.addServices( EhCacheService.class ).setMetaInfo( options );
+}
+</code></pre>
+ <p>
+ Not all EntityStore implementations use the Cache extension, so check the implementation details of the
+ EntityStore whether the cache extension can bring any benefits or not.
+ </p>

+ <h2>Common API.</h2>
+ <p>
+ The Common API package is a collection of really low-level types needed at the core of the Zest™ Runtime. It is also
+ a collection of types that are not particularly cohesive, and effectively this package contains the loose ends
+ that does not belong elsewhere.
+ </p>
+ <p>
+ In this package, you can safely ignore the following classes;
+ </p>
+ <ul>
+ <li>MetaInfo</li>
+ <li>QualifiedName</li>
+ <li>TypeName</li>
+ </ul>
+ <p>UNLESS you are into deep integration into the Zest™ Runtime.</p>
+
+ <h3>@AppliesTo and AppliesToFilter</h3>
+ <p>
+ This tandem of interface + annotation are primarily used for Generic Fragments, to indicate which methods on the
+ interface the fragment should be applied to.
+ </p>
+
+ <h3>@Optional</h3>
+ <p>
+ In Zest™, method arguments, property values and injected fields are not allowed to be null by default. To allow
+ any of these to be null, i.e. undeclared, it is required that the argument, field or method is marked with the
+ @Optional annotation.
+ </p>
+
+ <h3>@UseDefaults</h3>
+ <p>
+ Since null is not allowed without the @Optional annotation, it can sometimes by tedious to initialize all
+ the property values. And the @UseDefaults annotation allows us to declare that Zest™ should set the Property
+ to a default value. These are either the pre-defined ones, or can be set per property declaration during the
+ assembly.
+ </p>
+
+ <h3>@Visibility</h3>
+ <p>
+ Visibility is another innovative concept in Zest™, which leverage the structure system (Application, Layer, Module)
+ to limit the 'reach' when requesting composites and objects. The Visibility is declared per Composite/Object,
+ preferably in the most restrictive mode possible, and the visibility resolver will ensure a predictable resolution
+ algorithm;
+ </p>
+ <ol>
+ <li>Search the module of the caller first. If one and only one composite type fulfilling the request is available
+ return that to the caller. If two or more are found, throw an AmbiguousTypeException. If no composite found
+ continue to the next step.
+ </li>
+ <li>Search all modules in the Layer of the caller for composite that has a declaration other than
+ <code>Visibility.module</code>. If one and only one composite type fulfilling the request is available
+ return that to the caller. If two or more are found, throw an AmbiguousTypeException. If no composite found
+ continue to the next step.
+ </li>
+ <li>Search all modules in the Layer(s) (if any) directly below of the caller for composite that has a declaration of
+ <code>Visibility.application</code>. If one and only one composite type fulfilling the request is available
+ return that to the caller. If two or more are found, throw an AmbiguousTypeException. If no composite found
+ continue to the next step.
+ </li>
+ <li>Throw an NoSuchCompositeException (or related) exception.</li>
