/**
* A placeholder for a filter implementation that implements a greater or equal filter.
* This placeholder can be used in a {@link AttributeFilter} annotation.
*
* A greater or equal filter accepts a class and an object. The class is interpreted as the expected type. This is used to convert the
* object parameter. The following conversion are done based on the expected type in the right order.
*
* <ul>
* <li>If the value is a {@link SubqueryProvider}, the filter will create a subquery restriction.</li>
* <li>If the value is an instance of the expected type, the value will be used in the restriction as is.</li>
* <li>If the parsing of the {@linkplain Object#toString()} representation of the object to the expected type is successful,
* the parsed value will be used in the restriction.</li>
* <li>If the parsing of the object fails, an {@link IllegalArgumentException} is thrown.</li>
* </ul>
