[OpenWalnut-Dev] the WAssert macro

[reichenbach at informatik.uni-leipzig.de]

Hello,

revision 1698 (b9d2067c708a) adds the macro WAssert, that can be used to
perform run-time checks on your data.

To use the macro, common/WAssert.h needs to be included in your .cpp.

If WASSERT_AS_CASSERT is defined before including the header, the  
macro will act like a c-assertion, else a WException will be thrown.

In the current implementation, the macro has 2 parameters. The first is an
expression that can be evaluated to a boolean value. The second one is  
an optional message. If you do not want to add a message, simply set  
the second
parameter to "".

In any case, the expression that failed as well as the position of the WAssert
statement (file and line number) are reported.

Example:

   WAssert( true == false, "" );
   WAssert( someboolean == true, "This is an example." );

Best Regards,
    André
