Hi,

 

I need to make a collection of allowed items.. Something like this:

 

# Configuration file

 

allowed {

    item1

    item2

    .......

    .......

}

 

And then, the whole collection load into Set<String>

 

Thanks

You can use configuration's String list, load/save it as list and convert to Set<String>.

Use a string list/array getter for the property, then create a

Set<String>

from the

String[]

using

ImmutableSet.copyOf

.

Ok I made this:

 

List<String> types = new ArrayList<String>();

 

types = Arrays.asList(config.getStringList("", "Allowed", new String[]{"item1", "item2", "item3"}, "Comment"));

 

It works perfectly, but if I add new item into config, it throws this error:

 

An exception occurred while loading config file mod.cfg. This file will be renamed to mod.cfg_20160825_141457.errored and a new config file will be generated.

Post the full stack trace.

Ok I fixed it..

 

Just use Property and ImmutableList

 

Property property = config.get("Data", "Allowed", new String[]{"item1", "item2", "item3"});
list = ImmutableList.copyOf(property.getStringList());

Please use strongly typed lists.
