Overriding Retrieve Method in Remote Objects

Question

When using remote objects, is it possible to override the default retrieve method so that nothing is returned unless a where query is present?

Answer 1

You can do that.

First you need to override the retrieve method in your definition:

retrieve="{!$RemoteAction.<YOURCLASSNAME>.retrieve}"

secondly you need to implement that class and method:

@RemoteAction
public static Map<String, Object> retrieve(String type,
                                         List<String> fields,
                                         Map<String, Object> criteria) {
  Map<String, Object> result = RemoteObjectController.retrieve(type,
                                                               fields,
                                                               criteria);

  return result;
}

then just add your if clause inside that method (the example just executes the original method.
