Make OtlpExporter class internal #1528

Merged

The constructor on all of our exporter classes is internal. I think making the class internal is the right thing to do. If so, I can expand this PR to make this change to zipkin, jaeger, etc.

the ctor() was already internal, so we wont break anyone right?

By the class being public, the type is visible, so a user can type var exporter = new OtlpExporter() ... but with no way to construct it, is there any value in exposing it?

Ah, sorry, I misread your question... it does not appear to break anything.

Agree.
I was thinking -- if a user want to write own Batching/SimpleExportprocessor, then they wont be able to do that, as they cannot construct the exporter. But its okay, as spec talks about only 2 ExportingProcessors. and #1504 will solve customization issues as well.

Right, if #1504 is the pattern we want going forward, then I don't think we need to expose the classes. We could always re-expose the classes with a public constructor if we saw some need for that in the future.
