-----------------------------------------------------
On second thought - there are methods:
{noformat}
load()
reload()
save()
{noformat}
in FileConfiguration. Some kind of CachedConfiguration interface would probably be more generic.

-----------------------------------------------------
I was thinking along:
---------------------
Configuration.setProperties(Map)
---------------------
I have a configuration with costly write operation.
Calling setProperty(...) in cycle takes some time.
I think DatabaseConfiguration would also benefit from it. Like CONFIGURATION-180

----------------------------------------------
What's the use case for setting multiple properties in one call?
For the method signature, I suggest this:
{code:java}setProperty(Map.Entry<String, Object>... entries){code}
that would give this very nice syntax:
{code:java}
conf.setProperty(new AbstractMap.SimpleEntry<String, Object>("key1", "value1"),
new AbstractMap.SimpleEntry<String, Object>("key2", "value2"))
{code}
uh no, forget it ;)
We might as well use a Map:
{code:java}setProperties(Map<String, Object> entries){code}
which gives:
{code:java}
Map entries = new HashMap();
entries.put("key1", "value1");
entries.put("key2", "value2");
conf.setProperties(entries);
{code}
but that's not really simpler than:
{code:java}
conf.setProperty("key1", "value1");
conf.setProperty("key2", "value2");
{code}
I don't think there will be a decent solution until Java has a simple map creation syntax like the one proposed by the project Coin:
{code:java}
conf.setProperty({"key1":"value1", "key2":"value2"});
{code}

--------------------------------------------
Yes, this could be useful. Which concrete API or method signature do you suggest?
