    • findSuperType

      public final JavaType findSuperType(Class<?> rawTarget)
      Description copied from class: JavaType
      Method that may be called to find representation of given type within type hierarchy of this type: either this type (if this type has given erased type), one of its supertypes that has the erased types, or null if target is neither this type or any of its supertypes.
      Specified by:

    • serializeWithType

      public void serializeWithType(com.fasterxml.jackson.core.JsonGenerator g, SerializerProvider provider, TypeSerializer typeSer) throws IOException
      Description copied from interface: JsonSerializable
      Serialization method called when additional type information is expected to be included in serialization, for deserialization to use.

      Usually implementation consists of a call to TypeSerializer.writeTypePrefix(JsonGenerator, WritableTypeId) followed by serialization of contents, followed by a call to TypeSerializer.writeTypeSuffix(JsonGenerator, WritableTypeId)). Details of the type id argument to pass depend on shape of JSON Object used (Array, Object or scalar like String/Number/Boolean).

      Note that some types (most notably, "natural" types: String, Integer, Double and Boolean) never include type information.

      Specified by:
      serializeWithType in interface JsonSerializable
      Throws:
      IOException

    • serialize

      public void serialize(com.fasterxml.jackson.core.JsonGenerator gen, SerializerProvider provider) throws IOException
      Description copied from interface: JsonSerializable
      Serialization method called when no additional type information is to be included in serialization.
      Specified by:
      serialize in interface JsonSerializable
      Throws:
      IOException

    • _classSignature

      protected static StringBuilder _classSignature(Class<?> cls, StringBuilder sb, boolean trailingSemicolon)
      Parameters:
      trailingSemicolon - Whether to add trailing semicolon for non-primitive (reference) types or not

    • _bogusSuperClass

      protected static JavaType _bogusSuperClass(Class<?> cls)
      Internal helper method used to figure out nominal super-class for deprecated factory methods / constructors, where we are not given properly resolved supertype hierarchy. Will basically give `JavaType` for `java.lang.Object` for classes other than `java.lafgn.Object`; null for others.
      Since:
      2.7

    • _hasNTypeParameters

      protected boolean _hasNTypeParameters(int count)
