| -COMPONENT OVERVIEW- |
| |
| Configuration registry |
| * At initialization, each request adapter (servlet, filter, et cetera), adds its configuration to a single registry at a global location under a unique key. |
| |
| Command Context |
| * Extends CoR Context to encapsulate framework members needed to process request and render response |
| |
| Request Adapter (servlet module, portlet, SOAP, mock) |
| * Receives request from container (or TestRunner) |
| * Normalizes request path (masks pattern registered with container) |
| * Creates context to wrap request and response objects |
| * Adds reference to its configuration (stored in global registry) |
| * Invokes Controller |
| * When control returns, dispatches to Location (if any) |
| |
| Controller |
| * Receives context and selects the matching mapping |
| * Adds reference to mapping instance to context |
| * Sets mapping's default Location to context |
| * Removes any expired messages from context |
| * Invokes processor for mapping |
| |
| Processor |
| * Invokes series of methods ("Chain of Commands") to handle request. The default series includes |
| * Multipart |
| * Locale |
| * ContentType |
| * NoCache |
| * PreProcess |
| * Roles |
| * InputHandler |
| * Cancel |
| * Reset |
| * Populate |
| * Validate |
| * Invalid |
| * MappingHandler |
| * Command | Script |
| * Invoke business logic |
| * Affect context state |
| * Identify resource to render response |
| * Location |
| * Identify resource to render response |
| |
| ExceptionHandler |
| * Intercept any Exception thrown by Processor and set Location to designated error page. |
| |
| Tags/Tools |
| * Reference Command Context (stored in request) to access framework members |
| |
| Server Pages |
| * Utilize tags and tools to render dynamic data. |
