Type inheritance

Gentee allows you to inherit structure types. For this purpose you have to specify an attribute inherit with the name of the parent type.

type mytype <inherit = str>
   uint i
   uint k

Specify an empty curly brackets or a collon if a new type does not have additional fields.

type mynewtype <inherit = mytype> :

You cannot inherit base numeric types and the type reserved. The type inheritance allows you to get fields of any parent type.

type my <inherit = mytype>
   str name
my m

Also, you can call methods or functions of all parent types. The compiler finds a suitable method or function when you call some function or method. For example, there are the following functions

func print( mytype mt, uint i )
   print("MYTYPE PARAMETER = \( mt.i + i )\n")

func print( mytype mt )
   print("MYTYPE = \( mt.i )\n")

func print( my m )
   print("MY = \( m.i )\n")

You have

my mm

print( mm, 20 )
print( mm )

The first print outputs MYTYPE PARAMETER = 20 and the second print outputs MY = 0, but nor MYTYPE = 0. The situation with methods or operators is like. If you need to call just a parent method or a function then use the typecasting operator '->' with the parent typename. print( mm->mytype ) displays MYTYPE = 0.

So, Gentee gives you the such main object-oriented programming features as the inheritance and the polymorphism.
