Package org.springframework.cloud.stream.binding

Interface StreamListenerParameterAdapter<A,​B>

  • Type Parameters:
    A - adapter type
    B - binding result type
    public interface StreamListenerParameterAdapter<A,​B>
    Strategy for adapting a method argument type annotated with Input or Output from a binding type (e.g. MessageChannel) supported by an existing binder. This is a framework extension and is not primarily intended for use by end-users.

      • supports

        boolean supports​(Class<?> bindingTargetType,
                 org.springframework.core.MethodParameter methodParameter)
        Return true if the conversion from the binding target type to the argument type is supported.
        Parameters:
        bindingTargetType - the binding target type
        methodParameter - the method parameter for which the conversion is performed
        Returns:
        true if the conversion is supported

      • adapt

        A adapt​(B bindingTarget,
        org.springframework.core.MethodParameter parameter)
        Adapts the binding target to the argument type. The result will be passed as argument to a method annotated with StreamListener when used for setting up a pipeline.
        Parameters:
        bindingTarget - the binding target
        parameter - the method parameter for which the conversion is performed
        Returns:
        an instance of the parameter type, which will be passed to the method
