AbstractOverrideSource
public interface OverrideSource extends Source<OverrideSource.OverrideData>, java.util.function.Supplier<OverrideSource>
A config override setting provides an alternate, or overriding, value for a
config element based on the element's key. Implementations of this interface
furnish override settings as OverrideSource.OverrideData
objects.
The OverrideSource.OverrideData.data
method returns a List
of pairs, each of
which contains a Predicate
which evaluates the config key and a
String
which is the overriding value to be used if the predicate is
true
. The config system applies overrides before it applies
filters
, and it applies only the first matching override
it finds.
The config override mechanism affects existing Config
nodes that come
from a ConfigSource
. The override mechanism cannot create additional
Config
nodes, only modify existing ones.
