[magnolia-dev] [JIRA] (MAGNOLIA-5054) Generic return type of AutoGenerationConfiguration.getGeneratorClass() does not allow custom implementations

Thu, 23 May 2013 02:10:36 -0700

Issue Type: Bug Bug
Assignee: Unassigned
Components: rendering
Created: 23/May/13 11:08 AM
Description:

The return type is:

Class<Generator<AutoGenerationConfiguration>> getGeneratorClass();



Which means that it has to be this exact class, or interface as it is in this case. That's obviously not what we want. We want it to be a class that implements the Generator interface with a custom configuration class as its type parameter.



It should be:





Class<? extends Generator<? extends AutoGenerationConfiguration>> getGeneratorClass();






Here's an example of the problem:





    public static class MyAutoGenerationConfiguration implements AutoGenerationConfiguration {

        @Override
        public Map<String, Object> getContent() {
            return null;
        }

        @Override
        public Class<Generator<AutoGenerationConfiguration>> getGeneratorClass() {
            return MyGenerator.class; // DOES NOT COMPILE
        }
    }

    public static class MyGenerator implements Generator<AutoGenerationConfiguration> {

        @Override
        public void generate(AutoGenerationConfiguration configuration) throws RenderException {
        }
    }
