All Implemented Interfaces:

Cloneable, javax.servlet.jsp.tagext.JspTag, javax.servlet.jsp.tagext.Tag

public class BooleanDecorator
extends BaseDecorator
implements Cloneable

Lookup in the context messages for common boolean items for textual display or HTML tag building i.e. "Yes" - "No" "On" - "Off" "/image/icon_on.gif" - "/image/icon_off.gif" If you have a property return a Boolean, you can do In the properties file have these keys present: resource.application.inventory.service.ispresent.true=YES resource.application.inventory.service.ispresent.false=NO To Do: Make this work with boolean's as well as Booleans so you can have some more fun. For instance, the "flag" might be a method that has indexed bits i. e. in the example below getFlags() must might return java.util.BitSet whose first bit we're interested in In the properties file, have these keys present: application.properties.key.prefix.true=Yes application.properties.key.prefix.false=No
