properties in mixins

Postby kobi7 » Sun Nov 11, 2012 4:24 am

the following code doesn't compile due to "error: Cannot use the from form of a property inside an interface declaration."
refering to the getter.

Are properties prohibited in mixins, or is this a mistake?

Code: Select all
mixin ManageAttitude

   var _attitude as decimal
   get attitude from _attitude

   def happierBy(n as decimal)
      require
         n >= 0.0 and n<=1.0
      body
         _attitude = Math.min(1.0, .attitude + n) # atmost

   def sadderBy(n as decimal)
      require
         n >= 0.0 and n<=1.0
      body
         _attitude = Math.max(0.0, .attitude - n) # atleast


Thanks, kobi

Properties are definitely allowed. This is a code gen bug. Until it's fixed, the workaround is to write the code for the property like so:
mixin ManageAttitude

var _attitude as decimal
get attitude as decimal
return _attitude
