Macro Definition Documentation

#define ADD_INSTANCE_COUNTER

Value:

public:\
    static int s_numberOfInstances;\
    static int s_totalNumberOfInstances;\
private:

Macro definition that adds static member variables to a class to keep track of the number of instances created from this class.

Variables added to a class using this macro will have to be initialized in the implementation file of the class using the INIT_INSTANCE_COUNTER macro.

See Also: INIT_INSTANCE_COUNTER

#define INIT_INSTANCE_COUNTER ( className )

Value:

int className::s_numberOfInstances = 0;\

int className::s_totalNumberOfInstances = 0;

Macro definition that initializes the static member variables added to a class using the ADD_INSTANCE_COUNTER macro.

To be added in the implementation file of the class.

Parameters

className The name of the class to which the static member variables have been added.

See Also: ADD_INSTANCE_COUNTER

#define INC_INSTANCE_COUNTER

Value:

++s_numberOfInstances;\

++s_totalNumberOfInstances;

Macro definition that updates the static member variables added to a class using the ADD_INSTANCE_COUNTER macro.

Should be called when an instance of this class is created (e.g. by adding it to constructors of the class).

See Also: DEC_INSTANCE_COUNTER

#define DEC_INSTANCE_COUNTER --s_numberOfInstances;

Macro definition that updates the static member variables added to a class using the ADD_INSTANCE_COUNTER macro.

Should be called when an instance of this class is destroyed (e.g. by adding it to destructors of the class).

See Also: INC_INSTANCE_COUNTER

#define SHOW_INSTANCE_COUNTER ( className ) Log::debug(QString("%1 of %2 instances of class " #className " left").arg(className::s_numberOfInstances).arg(className::s_totalNumberOfInstances), "main");

Macro definition that displays the statistics about the number of instances created from a class to which instance counter member variables have been added using the ADD_INSTANCE_COUNTER macro.

Parameters

className The name of the class to which the static member variables have been added.

See Also: ADD_INSTANCE_COUNTER
