The Output Framework

The next set of methods are used to handle the output of all parts of the Agent System. At default the AgentSystem just prints all on the STDOUT stream (java.lang.System.out), but if a (or more) admin System Agent has registered the AdminIFace, which provides all these methods, the System sends the output to the admin SysAgents. The main intent of this output framework is for an Admin System Agent which can now provide a history for each part of the System. The GUIAdmin (see Section on page ) is a good example to show the use of this concept. In detail the output framework consists of these methods:

• [print(String]s) Is used for the output of the System (class AgentSystem).
• [println(String]s) Is also used for the output of the System but inserts a newline at the end of the string.
• [print(Exception]e) Is used to print the checked exception. This could be used to open an error window with the the exception description.
• [print(AgentID]id, String s) Is used for the output of all Agents (including System Agents).
• [println(AgentID]id, String s) The same as above but with newline on the end.
• [print(AgentID]id, Exception e) Is used to print a catched exception of the Agent.
