 The above figure depicts a simplified model of working:

...

ModelProvider (described in details at ModelProvider) is a core interface in Slice and is used for providing objects (models). Its functionality is very similar to injector's getInstance(); however it is extended by a resource, so that object fields can be mapped using specified resource (or path). A simple use of ModelProvider:

ModelProvider modelProvider = injector.getInstance(ModelProvider.class);
TextModel model = modelProvider.get(TextModel.class, request.getResource());

...

The @SliceResource annotation is used for marking classes which should be mapped from current resource by built-in object-resource Mapper. An example class looks like this:

@SliceResource
public class TextModel {
 
    @JcrProperty
    private String text;
 
    public String getText() {
        return text;
    }
}

...

The three subsections above described very briefly core mechanisms of Slice. To sum it up, take a look at the image below which put all these things together.Image Removed
