-----------------------------------------
Summary: 2. Migrate hand-written class loader to Poco::ClassLoader
Key: MINIFICPP-1473
URL: https://issues.apache.org/jira/browse/MINIFICPP-1473
Project: Apache NiFi MiNiFi C++
Issue Type: New Feature
Reporter: Ferenc Gerlits
Our current class loading infrastructure is quite confusing, and relies on
static self-registry of classes.
Poco::ClassLoader looks like a robust 3rd-party implementation of the same
thing, which
* would be easier to adapt to the shared-library-plugin world;
* and already supports both Windows and Linux/Mac, so we can hide OS-specific
differences (which are handled by our hand-crafted code, but it's not clear how
well).
As part of this, we should get rid of the static self-registry, which won't
work with plugins.
TODO: may need to be broken down further
* bring in the Poco library: Foundation only, strip out everything else
* rewrite the classloader to use Poco::ClassLoader
* remove static self-registry and load the classes explicitly when needed
TODO: Verify that Poco::ClassLoader can load classes from whole-archived static
libraries inside the executable itself. If it cannot, then this step will need
to be moved to later.
