Detailed Description
Extension function spec, used for complicated argument custom functions.
Provides the ability to handle all argument type checking and processing manually. Derive from this class and then make your own SeExprFunc that takes this object. This is necessary if you need string arguments or you have variable numbers of arguments. See SeExprBuiltins.h for some examples

Constructor & Destructor Documentation
| SeExprFuncX::SeExprFuncX | ( | const bool | threadSafe | ) | [inline] |
Create an SeExprFuncX. If the functions and type checking you implement is thread safe your derived class should call this with true. If not, then false. If you mark a function as thread unsafe, and it is used in an expression then bool SeExpression::isThreadSafe() will return false and the controlling software should not attempt to run multiple threads of an expression.
