Detailed Description

template<typename T>
class capd::auxil::Counter< T >

Counter add to each object of given class unique id and also counts number of objects created and existing.

This class is for debugging purpose mainly. It reports each creation and destruction to capd::slog stream. You can turn on/off its output by

capd::slog.show = true/false; 

For example output: < + A [34][12] > means that there was created object (+) of class A with id=34 (we start with id=1) and that at this moment there exist 12 objects. Destruction is denoted by '-' and substitution by '='.

To add counter to your class A simply inherit from Counter i.e.:

class A: public capd::auxil::Counter<A>{
  ...
};

Remarks

If class A defines its own copy constructor and/or operator= and you do not manually call corresponding functions from Counter than default constructor will be reported for copy constructor and nothing for =.
