AutoCast Struct Reference

Description:

This built-in compiler plug-in of ALib Expressions, performs auto-casts only if two different types are given. In this case, the following casts are performed:

1. If one argument is of type Types::String, the other is converted to string. The expression function returned for (optional) de-compilation is "String()".
2. If one argument is of type Types::Float and the other of type Types::Integer, the integral value is cast to floating point. The expression function returned for (optional) de-compilation is "Float()".
3. If one argument is of type Types::Float and the other of type Types::Boolean, the boolean value is cast to floating point. The expression function returned for (optional) de-compilation is "Float()".
4. If one argument is of type Types::Integer and the other of type Types::Boolean, the boolean value is cast to integer. The expression function returned for (optional) de-compilation is "Integer()".
5. If one argument is of type Types::Boolean, the other is converted to boolean using an internal callback function that simply invokes box-function FIsTrue. The expression function returned for (optional) de-compilation is "Boolean()".
