Handling Object Type as Dictionary for oneOf and anyOf in Java SDKs

· 2 min read

OpenAPI Specification allows you to add an object type in oneOf and anyOf in Java SDKs. Defining an object type means any key/value pair is accepted. Object type in Java means it can refer to any instance, as Object is the root class. Therefore, this change enforces that for any object type case falling under oneOf and anyOf, the Java SDK will treat it as Map.

oneOf​

Here is how you can define an Object type in oneOf in OpenAPI specification:

"oneOf": [
  {
    "type": "number"
  },
  {
    "type": "boolean"
  },
  {
    "type": "object"
  }
]

In Java SDKs, the corresponding type of the Object will be Map (i.e. key/value pairs) and can be initialized with any key/value pair as shown below:

    Map<String, Object> object = new HashMap<>();
    object.put("key", "value");
    OneOfContainer oneOfContainer = OneOfContainer.fromObject(object); // Initialized with the object case in oneOf

anyOf​

For anyOf, you can define an Object type the same way as for oneOf, as shown:

"anyOf": [
  {
    "type": "number"
  },
  {
    "type": "boolean"
  },
  {
    "type": "object"
  }
]

In Java SDKs, you can consume anyOf cases as explained in this code sample:

    Map<String, Object> object = new HashMap<>();
    object.put("key", "value");
    AnyOfContainer anyOfContainer = AnyOfContainer.fromObject(object); // Initialized with the object case in anyOf
