hoglet, in it's default deployment, comes with a number of core handlers that perform specific tasks. A handler is an arbitrary piece of Java code that implements the org.hoglet.handlers.core.TagHandler interface.

They are:

Class	Purpose	Suggested Tag	Thread Safe
Text Handler	Allows the content of a tag to be wrapped in a text template (usually HTML).	Any	Yes
Code Handler	Allows source code to be formatted and keywords for the relevant language to be highlighted, also supports outputting of line numbers.	Any - should be name of language, i.e. java, c, perl etc.	Yes
Link Handler	Allows a link to be included.	link	Yes
JavaDoc Handler	Allows a link to a Javadoc reference to be included.	javadoc	Yes
XML Handler	Allows a chunk of valid XML to be formatted and highlighted.	xml	Yes
Table Row Handler	Allows a row of a table to be generated.	tr	Yes
Hoglet Handler	Allows hoglet tags to be formatted and highlighted.	hoglet	Yes

Each of the handlers above implement the JDOMInitable which means that they can be initialised using a JDOM  org.jdom.Element. See: XML Configured Processor for more details.
