[opencms-dev] How set set access control entries for a resource programatically?

How set set access control entries for a resource programatically?

I learned from the mailing list in another context that it's usually
not necessary to ever use/call the CmsSecurityManager and it's
instantiation method directly.

So, what's the correct way to apply or remove access control entries
for a resource?
I'm looking for methods that do the same as:

CmsSecurityManager.newInstance(...).getAccessControlEntries
CmsSecurityManager.newInstance(..).copyAccessControlEntries
CmsSecurityManager.newInstance(...).removeAccessControlEntry

I couldn't find anything through the org.opencms.main.OpenCms class,
for example: OpenCms.getResourceManager() doesn't give me any suitable
methods, neither does the CmsFile/CmsResource .

Thanks,
Mathias
