registerAsImmutable

void registerAsImmutable(Object object)

Hint to the native image generator that the given object is immutable at runtime, i.e., can be placed in a read-only section of the native image heap.

registerAsImmutable

void registerAsImmutable(Object root,
 Predicate<Object> includeObject)
