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)
while subsequent ones have only the same name and the required is partial clause
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
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
