java.lang.Object

com.redhat.rhn.frontend.action.configuration.BaseConfigFilter

All Implemented Interfaces:

ListFilter

Direct Known Subclasses:

ConfigChannelFilter, ConfigFileFilter, ConfigSystemFilter

public abstract class BaseConfigFilter
extends java.lang.Object
implements ListFilter

Allows us to filter config lists. All the concrete class needs to do is provide a list of bean-ready field names (ie, if getFoo() exists in the Dto, "foo" is the field name), and an I18N msg of the form "configfilter.method.<field>", and the base class will do the rest. ConfigFileFilter
