All Implemented Interfaces:

Accountable

public class DefaultWrapperModel
extends WrapperModel

A scoring model that fetches the wrapped model from SolrResourceLoader.

This model uses SolrResourceLoader.openResource(String) for fetching the wrapped model. If you give a relative path for params/resource, this model will try to load the wrapped model from the instance directory (i.e. ${solr.solr.home}). Otherwise, seek through classpaths.

Example configuration:

{
  "class": "org.apache.solr.ltr.model.DefaultWrapperModel",
  "name": "myWrapperModelName",
  "params": {
    "resource": "models/myModel.json"
  }
}
