Class InsertAttributeModel

java.lang.Object
  org.apache.tiles.template.InsertAttributeModel

public class InsertAttributeModel
extends Object

Inserts the value of an attribute into the page.

This tag can be flexibly used to insert the value of an attribute into a page. As in other usages in Tiles, every attribute can be determined to have a "type", either set explicitly when it was defined, or "computed". If the type is not explicit, then if the attribute value is a valid definition, it will be inserted as such. Otherwise, if it begins with a "/" character, it will be treated as a "template". Finally, if it has not otherwise been assigned a type, it will be treated as a String and included without any special handling.

Example :

 <code>
           <tiles:insertAttribute name="body" />
         </code>
