| <p>GraalVM Native Image compiles Java applications ahead of time. Because a native image cannot |
| discover every reflective access or generate serializers at runtime, Fory prepares serializers and |
| the required metadata while the image is built.</p> |
| <p><code>fory-core</code> contains Fory's GraalVM Feature and activates it automatically. Applications do not need |
| an additional Fory artifact or a <code>--features</code> option.</p> |
| <h2 class="anchor anchorTargetStickyNavbar_Vzrq" id=how-it-works>How It Works<a href=#how-it-works class=hash-link aria-label="Direct link to How It Works" title="Direct link to How It Works" translate=no></a></h2> |
| <p>Prepare each Fory instance during build-time class initialization:</p> |
| <ol> |
| <li class="">Store the Fory instance in a static field.</li> |
| <li class="">Register every application class that the native executable will serialize.</li> |
| <li class="">Call <code>fory.ensureSerializersCompiled()</code> after registration is complete.</li> |
| <li class="">Configure the owning class for build-time initialization.</li> |
| </ol> |
| <p>The Feature uses those registrations to provide the Native Image metadata required by Fory, |
| including metadata for private constructors, records, serializer constructors, and registered proxy |
| shapes. Application classes still need to be registered with Fory before serializers are compiled.</p> |
| <p>Fory disables asynchronous serializer compilation in a native image because runtime just-in-time |
| compilation is unavailable.</p> |
