  • Method Details

    • toObject

      T toObject(org.apache.flink.api.common.typeutils.TypeSerializer<T> serializer)
      Converts this RawValueData into a Java object.

      The given serializer is required because the "raw value" might be represented in a binary format and needs to be deserialized first.

      Note: The returned Java object may be reused.

    • toBytes

      byte[] toBytes(org.apache.flink.api.common.typeutils.TypeSerializer<T> serializer)
      Converts this RawValueData into a byte array.

      The given serializer is required because the "raw value" might be still be a Java object and needs to be serialized first.

      Note: The returned byte array may be reused.

    • fromObject

      static <T> RawValueData<T> fromObject(T javaObject)
      Creates an instance of RawValueData from a Java object.

    • fromBytes

      static <T> RawValueData<T> fromBytes(byte[] bytes)
      Creates an instance of RawValueData from the given byte array.
