Examples of jade.content.ContentManager

jade.content.ContentManager
This class provides all methods to manage the content languages and ontologies "known" by a given agent and to fill and extract the content of an ACL message according to a given content language and ontology. Each agent has a ContentManager object accessible through the getContentManager() method of the Agent class. @author Federico Bergenti @author Govanni Caire - TILAB
