Interface BusinessFunction

All Superinterfaces:

Function, UndoableFunction

All Known Implementing Classes:

AbstractFunc

public interface BusinessFunction
extends UndoableFunction

Interface for business function enclosures to implement. Implementations should consider making the execute() method automatically calling the checkSecurity, validate, and checkBusinessRules methods and then performing the work of the function. Regardless, this work performed by this method is intended to be executed after checkSecurity, validate, and checkBusinessRules have been executed.
