Re: Exception Semantics question

I have a question on try throw semantics. This has
nothing to do with whether I should try or catch but
just the fact that I don't understand what is going
on here. Admittedly this is not any real code but a
scenario that I happened on by accident in experimenting
with writing my own exception class. The below code
compiles and runs with no errors but a newb like me
doesn't understand how. See comment on GlobalFunc

#include <iostream.h>

class ClassNoObject
{
 public:
 ClassNoObject(){}
 ~ClassNoObject(){}
 void ClsNoObjFunc()
  {
   cout << "no object class printing? \n";
  }

};

void GlobalFunc()
{ // How can throw construct a class definition with
   // no object, but seemingly does in the debugger ?
  // What is happening here ?

  cout << "fixing to throw ClassDefinition? \n";
  throw ClassNoObject();

}

void main(void)
{
 try
  {
   GlobalFunc();
  }

// The E instead of * E appears it is passing a copy,
// but a copy of what object ?

 catch( ClassNoObject E )
  {
   E.ClsNoObjFunc();
   cout << "Caught exception\n";
  }

}
