Interface GlobalFunction

public interface GlobalFunction

Provide an interface to allow script extensions to add a global function into the scripting environment. Any context, like the scripting environment via a ScriptContextDAO, should be passed to implementers of GlobalFunction via a constructor. This is not the recommended way of adding functions to the scripting enviroment. Instead you should add an object with the function you wish to call, and use the Object Orientiated way to call the method. (e.g. object.function(parameter)). Implementing GlobalFunction is the only way to a new global function to the scripting environment and exists for backwards compatibility.

Since:

ITIM 5.0
