  • Method Details

    • hasPolymorphism

      public boolean hasPolymorphism(Class<?> clazz)

    • getPolymorphismPropertiesToSerialize

      public Map.Entry<String,String>[] getPolymorphismPropertiesToSerialize(Class<?> clazz, Collection<String> otherProperties)

    • getTypeToDeserialize

      public Class<?> getTypeToDeserialize(jakarta.json.JsonObject jsonObject, Class<?> clazz)

    • getOrCreatePolymorphismTypeInfo

      public JsonbPolymorphismTypeInfo getOrCreatePolymorphismTypeInfo(Class<?> clazz)
      Looks up a JsonbPolymorphismTypeInfo from the cache or creates it for the given clazz if it supports polymorphism. This is the case if either one of these conditions is truthy:
      • clazz has an JsonbTypeInfo annotation
      • any class in the type hierarchy of clazz has an JsonbTypeInfo annotation
      Parameters:
      clazz - Class to inspect
      Returns:
      JsonbPolymorphismTypeInfo if the class supports polymorphism, null otherwise

    • validateJsonbPolymorphismAnnotations

      public void validateJsonbPolymorphismAnnotations(Class<?> classToValidate)
      Validates JsonbTypeInfo annotation on clazz and its parents (superclass/interfaces), see validateSubtypeCompatibility(Class), validateOnlyOneParentWithTypeInfo(Class) and validateNoTypeInfoKeyCollision(Class)
      Parameters:
      classToValidate - Class to validate
      Throws:
      jakarta.json.bind.JsonbException - validation failed

    • validateSubtypeCompatibility

      protected void validateSubtypeCompatibility(Class<?> classToValidate)
      Validation fails if any clazz and JsonbSubtype.type() aren't compatible.
      Parameters:
      classToValidate - Class to validate
      Throws:
      jakarta.json.bind.JsonbException - validation failed

    • validateOnlyOneParentWithTypeInfo

      protected void validateOnlyOneParentWithTypeInfo(Class<?> classToValidate)
      Validates that only one parent class (superclass + interfaces) has JsonbTypeInfo annotation
      Parameters:
      classToValidate - class to validate
      Throws:
      jakarta.json.bind.JsonbException - validation failed

    • validateNoTypeInfoKeyCollision

      protected void validateNoTypeInfoKeyCollision(Class<?> classToValidate)
      Validates that JsonbTypeInfo.key() is only defined once in type hierarchy. Assumes validateOnlyOneParentWithTypeInfo(Class) already passed.
      Parameters:
      classToValidate - class to validate
      Throws:
      jakarta.json.bind.JsonbException - validation failed
