Hello. Does anyone (especially Mr. @udalov) know what I should implement to access

org.jetbrains.kotlin.metadata.deserialization

? I am developing a project to rewrite `jackson-module-kotlin` with `kotlinx-metadata-jvm` and I noticed that the initialization process of

KmClass

is slow. It can't simply compare them because the processes are different, but a benchmark on initialization shows that the content under development takes about 1.2 times longer than the original (comparison on

o.w.ser.T_20Props.call

). https://github.com/ProjectMapK/jackson-module-kogera/pull/63 I looked at the profile of this process and found that most of it was the initialization process of

KmClass

. I think this difference is caused by

KmClass

reading all the information at once during initialization. The

KClassImpl

seems to lazily initialize only the information it needs. So I tried to create a

LazyKmClass

that lazily initializes only the necessary information, referring to

kotlinx.metadata.internal.ProtoBuf.Class.accept

. However, I am currently stuck because I can't figure out how to access

org.jetbrains.kotlin.metadata.data.deserialization.protoTypeTableUtil

. Any help would be greatly appreciated.

The

KClassImpl

seems to lazily initialize only the information it needs.

Nope, any non-trivial function or property of

KClass

requires

KClassImpl.data

to be computed which leads to deserialization of all metadata of the class (and sometimes of some other classes)

Thank you very much. I will take a closer look.
