Binary Object Serialization reconstructs object graphs, including registered application types, collections, polymorphic values, and optional shared references.
| Mode | Use it when | Start here |
|---|---|---|
| Xlang (default) | Bytes cross language boundaries | Xlang Serialization |
| Native | Every writer and reader uses one Fory implementation family | Native serialization |
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.
Read these pages before choosing the Fory API for a language:
- Core Concepts explains object graphs, types, schemas, references, polymorphism, and schema evolution across both modes.
- Xlang Serialization explains the portable format used by default and the rules that Fory implementations in different languages must share.
- Native Serialization explains when an implementation-specific native format is appropriate.
Choose a language to find its installation route, lifecycle, exact APIs, configuration, type registration, schema behavior, extensions, platforms, and troubleshooting:
