Class Keydata - similar entries from multiple sections?

[Wolfgang Alper]

Hello,
i am using commoncpp2-1.5.6.

How can i retrieve keys with the same name from a given section using the
Class Keydata?

Example:
[general]
port = 1234
host = www.myhost.com
[proxy]
port = 4321
host = www.proxy.com

running
load("/mydir/myfile/general");
and
load("/mydir/myfile/proxy]");

This leads to multiple port and host entries.

Of cause i can use getCount("port") and then iterate through the values, but
this assumes to know wether a section has a key "port".
Also i could use clrValue("port") to clear the value before loading a new
section, but this seems to be a bad workaround.

So how can i  query like "general/host" to get the value of host in the
[general] section or "proxy/host" to get the host in the [proxy] section?

Thanks

Wolfgang

Normally you would load each [] into a different keydata object.  If you
merge keydata sections into a single object instance, there is no means
to determine which instance it was loaded under.  Mostly merging is
meant to load "default" keys into a given object, and then override them
with live values.  At least that was the intended use.
