Package org.dspace.content.logic

Class TrueFilter

java.lang.Object

org.dspace.content.logic.TrueFilter

All Implemented Interfaces:

Filter, LogicalStatement, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware

public class TrueFilter
extends Object
implements Filter

Extremely simple filter that always returns true! Useful to pass to methods that expect a filter, in order to effectively say "all items". This could be configured in Spring XML but it is more stable and reliable to have it hard-coded here so that any broken configuration doesn't silently break parts of DSpace that expect it to work.
