DefaultFilter (DSpace Kernel :: API and Implementation 7.6.1 API)

java.lang.Object
- org.dspace.content.logic.DefaultFilter

All Implemented Interfaces:

Filter, LogicalStatement, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware
```
public class DefaultFilter
extends Object
implements Filter
```
The default filter, a very simple implementation of Filter / LogicalStatement The idea is to have this as a wrapper / root class for all logical operations, so it takes a single statement as a property (unlike an operator) and takes no parameters (unlike a condition)
