when will it invoke

[okou19900722]

private static <T> Map<String, T> convertMap(Map map) {
    if (map.isEmpty()) { 
      return (Map<String, T>) map; 
    } 
    Object elem = map.values().stream().findFirst().get(); 
    if (!(elem instanceof Map) && !(elem instanceof List)) { 
      return (Map<String, T>) map; 
    } else { 
      Function<Object, T> converter; 
      if (elem instanceof List) { 
        converter = object -> (T) new JsonArray((List) object); 
      } else { 
        converter = object -> (T) new JsonObject((Map) object); 
      } 
      return ((Map<String, T>) map).entrySet() 
       .stream() 
       .collect(Collectors.toMap(Map.Entry::getKey, converter::apply)); 
    } 
  }

this method in "proxygen.templ" but service method param Map only support Json or basic value，when will the converter invoker

sorry for bad english!I'm Chinese,Thank you

This method will be invoked in the generated code if a service method has a map parameter.

See https://github.com/vert-x3/vertx-service-proxy/blob/ecc1c64778702160d5a0eef34b4190f5121cbfc5/src/test/generated/io/vertx/serviceproxy/testmodel/TestServiceVertxEBProxy.java#L375

@tsegismont but the value elem cannot be Map or List，the method 'checkParamType' in ProxyModel check Map code is

if (raw.getName().equals(List.class.getName()) || raw.getName().equals(Set.class.getName())) {
      TypeInfo argument = ((ParameterizedTypeInfo) type).getArgs().get(0);
      if (argument.getKind().basic || argument.getKind().json || argument.getKind() == ClassKind.DATA_OBJECT) {
        return true;
      }
    } else if (raw.getName().equals(Map.class.getName())) {
      TypeInfo argument0 = ((ParameterizedTypeInfo) type).getArgs().get(0);
      if (!argument0.getName().equals(String.class.getName())) {
        return false;
      }
      TypeInfo argument1 = ((ParameterizedTypeInfo) type).getArgs().get(1);
      if (argument1.getKind().basic || argument1.getKind().json) {
        return true;
      }
    }

Key must be String, and Value must be base or json

[tsegismont]

You are confusing two things:

• ProxyModel.checkParamType is used only during the validation phase of code generation (checking the interface is valid)
• convertMap is used at runtime to convert a map parameter

@tsegismont yes , but do you think a invalid param will compile success when annotation processor process?
