Hello
I have created Map<String,My_Info_Class> during annotation processing. So Map is created during compile time. Is there any way I could access the same Map object I created in Different module ?

Most annotation processors exist mostly to do code generation. I would expect your annotation processor to probably write a code file that initializes the map you want, probably using something like KotlinPoet.

I am creating HashMap<String,ArrayList<DataClass>>

[Rohan Maity]

I am facing problem how to write the initialization for this Map

[Zach Klippenstein (he/him) [MOD]]

To be clear, are you saying your annotation processor is creating this map in memory as it's running and processing annotations?

[Rohan Maity]

Yes

[Rohan Maity]

Its creating in memory

[Rohan Maity]

I know ideal way would be to create a file and write the code for its initialization. But if in Memory map could be shared it would save the day

[Zach Klippenstein (he/him) [MOD]]

What do mean by access it in a different module? You mean when processing annotations on a different module?

So annotation processor is TunnelCompiler which makes the in memory Map and I want to access the map in Tunnel Module

[Zach Klippenstein (he/him) [MOD]]

Tunnel is a module that is processed by TunnelCompiler?

[Rohan Maity]

No,
Tunnel Compiler creates a MAP
and Tunnel just wants to use the ResultantMap

[Rohan Maity]

and In turn Tunnel is main module that is exposed as Library to client App

[Zach Klippenstein (he/him) [MOD]]

Is Tunnel a module that is expected to be included as a runtime dependency by code that is processed by TunnelCompiler? I'm trying to understand how the modules are related.

Yes it as added as dependency by Code that is processed by TunnelCompiler

[Zach Klippenstein (he/him) [MOD]]

Compilation/annotation processing happens completely independently from runtime. They happen at different times, in different processes, and probably even different physical machines. There is no way for the annotation processor to share memory with the VM that will eventually run the code it's processing.

[Rohan Maity]

Hmm I understood map is making in Compile Time and I wanted use it in runtime. But Still wanted to know if there is any possibilty to do so to share the memory.
Thanks for confirming @Zach Klippenstein (he/him) [MOD]

[Rohan Maity]

BTW I finally end up using KotlinPoet only
