```
public boolean appliesToProperty(Object propertyId)
```
    Returns true if a change in the named property may affect the filtering result. If some of the sub-filters are not in-memory filters, true is returned. By default, all sub-filters are iterated to check if any of them applies. If there are no sub-filters, false is returned - override in subclasses to change this behavior.
