boolean classImplementsMethod	(	Class	theClass,
		String	methodName
	)			[protected]

Class helperClassForClass	(	Class	helpedClass,
		String	helperFunction
	)			[protected]

Attempts to locate a helper class for helpedClass that implements helperFunction. If it cannot find a class called <className>Helper implementing helperFunction, it looks for a helper for each of the interfaces implemented by the class, and starts the process over with the superclass if that fails.

Parameters:

	helpedClass
	helperFunction

Returns:

synchronized void setHelperInstanceForClassInFrameworkNamed	(	Object	helperInstance,
		String	helperFunction,
		Class	targetObjectClass,
		String	frameworkName
	)			[protected]

Sets the helper object to use for the given class.

Parameters:

	helperInstance	an instance of the helper class (i.e. PersonHelper)
	helperFunction	the helper function being requested (i.e. formattedName)
	targetObjectClass	the class that maps to this helper instance (i.e. Person.class)
	frameworkName	the scoping of the helper instance (null, or "app" = global)

synchronized void setHelperInstanceForClassInFrameworkNamed	(	Object	helperInstance,
		Class	targetObjectClass,
		String	frameworkName
	)

Sets the helper object to use for the given class.

Parameters:

	helperInstance	an instance of the helper class (i.e. PersonHelper)
	targetObjectClass	the class that maps to this helper instance (i.e. Person.class)
	frameworkName	the scoping of the helper instance (null, or "app" = global)
