Common API.

+ 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. +

+ In this package, you can safely ignore the following classes; +

MetaInfo
QualifiedName
TypeName

UNLESS you are into deep integration into the Zest™ Runtime.

+ +

@AppliesTo and AppliesToFilter

+ This tandem of interface + annotation are primarily used for Generic Fragments, to indicate which methods on the + interface the fragment should be applied to. +

+ +

@Optional

+ 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. +

+ +

@UseDefaults

+ 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. +

+ +

@Visibility

+ 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; +

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. +
Search all modules in the Layer of the caller for composite that has a declaration other than + Visibility.module. 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. +
Search all modules in the Layer(s) (if any) directly below of the caller for composite that has a declaration of + Visibility.application. 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. +
Throw an NoSuchCompositeException (or related) exception.
