Interface PropertyProviderGenerator

All Known Implementing Classes:
  LocalePropertyProviderGenerator

    public interface PropertyProviderGenerator

An interface for generating a property provider JS implementation, rather than having it defined in a module file. Use it like this:

       <property-provider name="foo" generator="org.example.FooGenerator"/>

A default implementation in JS can be included inside the property-provider tag as usual, and will be used if the generator returns `null`.

Method Summary
`java.lang.String` | `generate(TreeLogger logger, java.util.SortedSet<java.lang.String> possibleValues, java.lang.String fallback, java.util.SortedSet<ConfigurationProperty> configProperties)` Generate a property provider.
