Object Serialization

Binary Object Serialization reconstructs object graphs, including registered application types, collections, polymorphic values, and optional shared references.

Choose a mode

Mode	Use it when	Start here
Xlang	Bytes cross runtime boundaries	Xlang mode
Native	Every writer and reader uses the same runtime family	Native mode

Xlang and native are the only object-serialization modes. Row Format is a random-access analytical representation, and Fory JSON is a Java JSON codec; use the format chooser when object reconstruction is not your goal.

Security

Before decoding externally supplied bytes, read Object Serialization Security. It covers accepted-type policy, registration, resource limits, transport responsibilities, and negative verification for both modes.
