module Neo4j::Shared
  # This module adds the `serialize` class method. It lets you store hashes and arrays in Neo4j properties.
  # Be aware that you won't be able to search within serialized properties and stuff use indexes. If you do a regex search for portion of a string
  # property, the search happens in Cypher and you may take a performance hit.
  #
  # See type_converters.rb for the serialization process.
