      public abstract StringBuilder getGenericSignature(StringBuilder sb)
      Specified by:
      getGenericSignature in class JavaType
      Parameters:
      sb - StringBuilder to append signature to
      Returns:
      StringBuilder that was passed in; returned to allow call chaining

    • getErasedSignature

      public abstract StringBuilder getErasedSignature(StringBuilder sb)
      Description copied from class: JavaType
      Method for accessing signature without generic type information, in form compatible with all versions of JVM, and specifically used for type descriptions when generating byte code.
      Specified by:
      getErasedSignature in class JavaType
      Parameters:
      sb - StringBuilder to append signature to
      Returns:
      StringBuilder that was passed in; returned to allow call chaining

      Description copied from class: JavaType
      Accessor for finding fully resolved parent class of this type, if it has one; null if not.
      Specified by:
      getSuperClass in class JavaType

    • getInterfaces

      public List<JavaType> getInterfaces()
      Description copied from class: JavaType

    • 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:
      findSuperType in class JavaType

    • serializeWithType

      public void serializeWithType(tools.jackson.core.JsonGenerator g, SerializationContext ctxt, TypeSerializer typeSer) throws tools.jackson.core.JacksonException
      Description copied from interface: JacksonSerializable
      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, SerializationContext, WritableTypeId) followed by serialization of contents, followed by a call to TypeSerializer.writeTypeSuffix(JsonGenerator, SerializationContext, 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 JacksonSerializable
      Throws:
      tools.jackson.core.JacksonException

    • serialize

      public void serialize(tools.jackson.core.JsonGenerator gen, SerializationContext ctxt) throws tools.jackson.core.JacksonException
      Description copied from interface: JacksonSerializable
      Serialization method called when no additional type information is to be included in serialization.
      Specified by:
      serialize in interface JacksonSerializable
      Throws:
      tools.jackson.core.JacksonException

    • _classSignature

      protected static StringBuilder _classSignature(Class<?> cls, StringBuilder sb, boolean trailingSemicolon)
      Parameters:

    • _hasNTypeParameters

      protected boolean _hasNTypeParameters(int count)
