Do executing table.get() inside endpoint co-processor invokes a observer's (preGet, postGet etc ) callbacks

I have a following test scenario.

Configured and added a co-processor endpoint. Endpoint implementation
includes a table.get() call. (And this table has observed added as well)

When i execute this end-point co-processor, where table.get() is a part of
endpoint implementation,* will is invoke preGet() and postGet() observer
callback as well...?*

Thank you.
Nilkanth.

Which region would be the recipient of the table.get() call ?

If that is a different region than the one the endpoint is activated on,
you should be aware of the potential deadlock issue.

Please take a look at CoprocessorHConnection.
