Detailed Description

dbUserFunction class is used to bind user defined functions to the database. This class contains list of all user functions declared by application and provides method for locating function by name and adding new user defined functions. User defined functions can have fro 0 till 3 parameters (of dbUserFunctionArgument type) and should return integer, boolean, real or string value. Type of the function is detected by overloaded constructors. User defined function descriptor is cerated by USER_FUNC macro.
