    • serialize

      public Data<byte[]> serialize(Object object, String format)
      Description copied from interface: Serializer
      Serializes the given object into a Data wrapper using the specified format.
      Specified by:
      serialize in interface Serializer
      Parameters:
      object - the object to serialize
      format - the desired serialization format (e.g. \"json\"); may be null
      Returns:
      serialized object as Data

    • deserialize

      public <I extends SerializedObject<byte[]>> Stream<DeserializingObject<byte[],I>> deserialize(Stream<I> stream, UnknownTypeStrategy unknownTypeStrategy)
      Description copied from interface: Serializer
      Upcasts and deserializes a stream of serialized objects. Each result in the output stream contains both a provider for the deserialized object and the serialized object after upcasting that is used as the source of the deserialized object.

      Deserialization is performed lazily. This means that actual conversion for a given result in the output stream only happens if DeserializingObject.getPayload() is invoked on the result. This has the advantage that a caller can inspect what type will be returned via

      invalid reference 
      DeserializingObject#getSerializedObject()
      before deciding to go through with the deserialization.

      You can specify whether deserialization of a result in the output stream should fail with a DeserializationException if a type is unknown (not a class). It is up to the implementation to determine what should happen if a type is unknown but the failOnUnknownType flag is false.

      Specified by:
      deserialize in interface Serializer
      Type Parameters:
      I - the type of the serialized object
      Parameters:
      stream - data input stream to deserialize
      unknownTypeStrategy - value that determines what to do when encountering unknown types
      Returns:
      a stream containing deserialization results

    • convert

      public <V> V convert(Object o, Type aClass)
      Description copied from interface: Serializer
      Converts a given object to another type using the serializer's object mapping rules.
      Specified by:
      convert in interface Serializer
      Type Parameters:
      V - the result type
      Parameters:
      o - the input value
      aClass - the target type
      Returns:
      the converted value

    • clone

      public <V> V clone(Object o)
      Description copied from interface: Serializer
      Creates a deep copy of the given object using serialization.
      Specified by:
      clone in interface Serializer
      Type Parameters:
      V - the type of the value
      Parameters:
      o - the object to clone
      Returns:
      a deep copy

    • registerUpcasters

      public Registration registerUpcasters(Object... casterCandidates)
      Description copied from interface: Serializer
      Registers one or more upcaster candidates.
      Specified by:

    • registerTypeCaster

      public Registration registerTypeCaster(String s, String s1)
      Description copied from interface: Serializer
      Registers a mapping from an old type identifier to a new one.
