Filter (DSpace Kernel :: API and Implementation 7.1.1 API)

All Superinterfaces:

LogicalStatement

All Known Implementing Classes:

DefaultFilter
```
public interface Filter
extends LogicalStatement
```
The interface for Filter currently doesn't add anything to LogicalStatement but inherits from it just to keep naming / reflection clean, and in case Filters should do anything additional in future. We need this as filters have to be specified in the spring configuration (item-filters.xml). Filters are the top level elements of the logic. Only logical statements that implement this interface are allowed to be the root element of a spring configuration (item-filters.xml) of this logic framework. A filter is just helping to differentiate between logical statement that can be used as root elements and logical statement that shouldn't be use as root element. A filter may contain only one substatement.
