public class ELGetTag
extends GetTag

This is the tag handler for <tiles-el:get>, which gets content from the request scope and either includes the content or prints it, depending upon the value of the content's direct attribute.

This tag is intended to be compatible with the same tag from Templates (David Geary). Implementation extends InsertTag for facility (no so well). The only difference is the default value of attribute 'ignore', which is true for this tag (default behavior of David Geary's templates).

This class is a subclass of the class org.apache.struts.taglib.tiles.GetTag which provides most of the described functionality. This subclass allows all attribute values to be specified as expressions utilizing the JavaServer Pages Standard Library expression language.
