Class DefaultFilter

java.lang.Object
org.dspace.content.logic.DefaultFilter
All Implemented Interfaces:
Filter, LogicalStatement, Aware, 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)
