public class IsEmpty
The IsEmpty droplet conditionally servlet renders one of its parameters based on
the value of its value parameter. If the value is null or if the object is "empty"
then the output parameter true
is rendered, otherwise the output parameter
false
is serviced.
Empty is defined by the following logic:
For Example:
<droplet bean="/atg/dynamo/droplet/IsEmpty">
<param name="value" value="param:someobject">
<oparam name="true">Some object is empty</oparam>
<oparam name="false">Some object is NOT empty</oparam>
</droplet>
