| 13: | * |
| 14: | * This controller is invoked only for routes that map to UI5 Resources. |
| 15: | * The current Ui5Context is provided by middleware and guarantees that |
| 16: | * `$context->artifact` is an instance of Ui5ResourceInterface. |
| 17: | * |
| 18: | * Responsibilities: |
| 19: | * - Resolve the ResourceDataProvider from the Resource artifact. |
| 20: | * - If the provider implements ParameterizableInterface, inject validated parameters. |
| 21: | * - If the provider implements ConfigurableInterface, inject resolved settings. |
| 22: | * - Execute the provider and return the result as JSON. |
| 23: | * |
| 24: | * Notes: |
| 25: | * - We assume the artifact in the context is always a Ui5ResourceInterface; |
| 26: | * no additional instanceof check is performed here. |
| 27: | * - Execution is side-effect free: Resources are read-only endpoints (GET). |
