62 Контракт представляет собой отображение модели предметной области на модель

diff changeset
63 ресурсов. Контракт описывает дерево ресурсов начиная с корневого ресурса,

66 Ресурсы состоят из нескольких описаний: C<ResourceContract>, C<OperationContract>
77a9934a44af sync, migrating to XML::Compile
cin
parents: 213
diff changeset
67 которые описываю отображение самих ресурсов и операций над ресурсами в предметную
77a9934a44af sync, migrating to XML::Compile
cin
parents: 213
diff changeset
68 область.

70 C<ResourceContract> представляет собой описание того, какой ресурс и с какими
77a9934a44af sync, migrating to XML::Compile
cin
parents: 213
diff changeset
71 параметрами должен быть создан. Например, может быть создан ресурс публикующий
77a9934a44af sync, migrating to XML::Compile
cin
parents: 213
diff changeset
72 методы родительского ресурса, или же ресурс может слжить контроллером для
77a9934a44af sync, migrating to XML::Compile
cin
parents: 213
diff changeset
73 работы с объектами предметной области.

75 C<OperationContract> описывает связь между методом объекта предметной области и
77a9934a44af sync, migrating to XML::Compile
cin
parents: 213
diff changeset
76 операцией возможной над ресурсом. Операция сводится к преобразованию запроса в
77a9934a44af sync, migrating to XML::Compile
cin
parents: 213
diff changeset
77 аргументы метода, затем вызову метода и преобразованию результата в ответ на запрос.
