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
