![]() ![]() Iâm not sure what other logic this would possibly break. Annotations are added as metadata tags that you attach to variables, parameters, and return values to inspect method return values, passed parameters, local. An annotation processor processes these annotations at compile time or runtime to provide functionality. When this is true, parameter values of type array or object generate separate parameters for each value of the array or key-value pair of the map. ![]() Annotations provide information to a program at compile time or at runtime based on which the program can take further action. I think the solution would be to remove the line where the parameter error is thrown (RequestFactory.java:331). An annotation is a construct associated with Java source code elements such as classes, methods, and variables. Instead I would rather use a custom annotation for this, that would be prettier: customData: String, then I should be able to extract the required data from the Invocation (I assume, i cannot test this yet) (where customdata looks like this: class CustomData(val customData: String)) If I do customData: CustomData in my api interface method, i can extract it using request.tag(CustomData::class.java). So instead, a slight bit more ugly, I can use the annotation to add whatever i want to the request. Jakob Jenkov Last update: Java annotations are used to provide meta data for your Java code. I wanted to also use custom parameter annotations, but then Retrofit throws an exception in class RequestFactory line 331 (version 2.6.2). In my situation I implement my own Call.Factory where i get the OkHttp requests, for which I can access my custom method annotations by calling request.tag(Invocation::class.java). For example, you can annotate the return type of a method, generic types, including generic type parameter bounds and generic type arguments. When implementing the AnnotationStrategy interface, you add instances of this class to. Same need, currently considering another solution, using the annotation instead. Data structure to represent a parameter of a Java annotation. The ElementType.TYPEPARAMETER target indicates that the annotation can be written on the declaration of a type variable (e.g., class Målass.
