CLASS / DATA, VAR... REQUIRED (New feature)

[Hurricane]

A suggestion, could someone add this feature to Harbour?!

syntax (hbclass.ch) and scope (HB_OO_CLSTP_REQUIRED)

This small change will help the class creator to automate this type of validation at strategic points.

CLASS TTest

   DATA cKey      INIT ''              REQUIRED

   DATA cModel    INIT '...ai_name...' REQUIRED

   DATA cURL                           REQUIRED

   ...

ENDCLASS

Once I'm done, I can share the code.

Changing the subject a little...

Is it possible to enable parameter checking for a method? The compiler will warn you when the implementation is different from the declaration.

I did some tests and I couldn't

CLASS TTest

   METHOD send( cURL )

ENDCLASS

METHOD send( cURL, xData ) CLASS TTest

   RETURN NIL

Regards,

Hurricane

Harbour is a dynamic non typed language and has constructs as ... or pcount() OR HB_APARAMS() (if i remember correctly) so it would be a bit strange to add the feature you request...

Btw, it would be a great addition! But it would be another language...

Hi,

>>Is it possible to enable parameter checking for a method? The compiler will warn you when the implementation is different from the declaration.

Use compiler option -w3

METHOD TableExist(cTable, a)

METHOD Function TableExist(cTable) CLASS ADOC
...

Compiler response is:

\Programas\dbAdo.prg(69) Warning W0001  Method <TableExist(cTable)> not declared or declaration mismatch in class <ADOC>
