Examples of org.apache.tiles.Definition

org.apache.tiles.Definition
A definition, i.e. a template with (completely or not) filled attributes. Attributes of a template can be defined with the help of this class.
It can be used as a data transfer object used for registering new definitions with the Container. @since Tiles 2.0 @version $Rev: 619574 $ $Date: 2008-02-07 20:09:33 +0100 (Thu, 07 Feb 2008) $
