AbstractUrlHandlerAdapter constructor

AbstractUrlHandlerAdapter(MethodArgumentResolverManager methodArgumentResolver, ReturnValueHandlerManager methodReturnValueHandler)

Creates a new AbstractUrlHandlerAdapter with the provided resolvers.

Parameters

• methodArgumentResolver: The resolver used to resolve handler arguments.
• methodReturnValueHandler: The handler used to process return values.

Abstract base implementation of HandlerAdapter for URL-based handler methods.

The AbstractUrlHandlerAdapter provides common invocation logic shared by all concrete handler adapters in the Jetleaf Web framework. It is responsible for managing:

• Argument resolution for reflective method calls.
• Handler invocation for DSL-defined routes and annotated controllers.
• Return value processing via composite return value handlers.

Responsibilities

• Handle invocation of:
  • RouteDslHandlerMethod — Jetleaf routing DSL functions.
  • AnnotatedHandlerMethod — Annotated controller methods.
  • FrameworkHandlerMethod — Internal Jetleaf framework endpoints.
• Integrate with argument and return value resolver strategies.
• Allow subclasses to extend behavior for custom handler types.

Lifecycle

Each request execution:

1. Resolves handler arguments (if applicable).
2. Invokes the underlying handler function or reflective method.
3. Delegates the result to the configured return value handler.

Example

final adapter = AnnotatedHandlerAdapter(argResolver, returnHandler);
await adapter.handle(request, response, controllerHandler);

Implementation

AbstractUrlHandlerAdapter(this.methodArgumentResolver, this.methodReturnValueHandler);
