= Partial Types =

Like C#, cobra allows you to specify a class as a partial Type allowing you to spread the definition of a class across multiple source files.
This is sometimes useful for large projects or classes made from partially computer generated code.

Each partial class definition must have the same description (inheritance/interfaces supported) and each must be explicitly marked as 
'''is partial'''.

More commonly the first portion of the partial class encountered has the full specification (inheritance, implementation, etc)[[BR]]
while subsequent ones have only the same name and the required '''is partial''' clause  

== Example==

in file1.cobra  

{{{
#!cobra
namespace PC
    interface IBCall
       def methodB

    class A inherits Object implements IBCall is partial
       var num = 0

       def main is shared
           a = A()
           a.methodA

       def methodA
           print 'A.methodA'
           .methodB
}}}

and in file2.cobra
{{{
#!cobra

namespace PC

    class A is partial 
       def methodB
           print 'A.methodB'
           _methodC

       def _methodC
           print 'A._methodC'
           .num = 99
}}}

program is built specifying both files but result is a single class
{{{
cobra file1.cobra file2.cobra
}}}
