   Public Member Functions
       void init_done (int code=0)
           After calling this, the object is destroyed without references.

   Static Public Member Functions
       static int set_default_tag (int tag)
           Set the default tag for when init_done is called.
       static void check (bool fatal=true)
           Check if all objects have called init_done.

   Protected Member Functions
       crefbase ()
           Constructor, which is called when an object is created.
       virtual ~crefbase ()
           Virtual destructor, which does nothing except allowing derived class to have a virtual
           destructor.

Detailed Description

       Circular-dependancy-protected reference-counting object base class.

       Objects which derive from this class are reference-counted in a way that detects
       dependency loops and destroys the entire loop when it is no longer externally referenced.
       For this, it is important that objects which contain pointers register them appropriately.

Member Function Documentation

   static void shevek::crefbase::check (boolfatal = true) [inline, static]
       Check if all objects have called init_done. When debugging is enabled, this function
       checks for all objects if they have called init_done. When debugging is not enabled, no
       list of objects is kept, and this check does nothing.

   void shevek::crefbase::init_done (intcode = 0) [inline]
       After calling this, the object is destroyed without references. On creation, an object
       does not have any references. To prevent immediate destruction, it is first in an
       initialisation phase. During that phase, it will not be destroyed, even if it has no
       references. This function should be called immeiately after creating the object (normally
       through crefptr::init): shevek::crefptr <foo> bar = foo::create ().init (); If code is not
       given or 0, the default tag (set with set_default_tag) will be used.

   static int shevek::crefbase::set_default_tag (inttag) [inline, static]
       Set the default tag for when init_done is called. If the tag is not set to 1, a message
       will be printed to standard error on destruction. The previous tag is returned. If tag is
       set to 0, the old value is not changed. The initial default value is 1.
