Detailed Description

The PROTECTED_DELETE base class provides a protected destructor. The only way to use PROTECTED_DELETE is inheritance: example: class LocalTraceBufferPool : public PROTECTED_DELETE Herited class destructor must stay protected. Normal use is:

• create an instance of herited class on the heap (new),
• use addObj(instance) to store the instance on the static list _objList,
• delete instance with deleteInstance(instance)

This class is utilised with GENERIC_DESTRUCTOR and DESTRUCTOR_OF, to program automatic deletion of objects at the end of the process, while keeping the possibility of an early destruction, if required. This is used for unit testing and trace mecanism.

PROTECTED_DELETE::~PROTECTED_DELETE (   )  [protected, virtual]

Herited classes have there own destructors

Member Function Documentation

void PROTECTED_DELETE::deleteInstance (  PROTECTED_DELETE *  anObject  )  [static]

deleteInstance deletes only once the object. Only object present on the static list of PROTECTED_DELETE* are deleted, then removed of the list. The operation is protected by a mutex.

void PROTECTED_DELETE::addObj (  PROTECTED_DELETE *  anObject  )  [static]

To allow a further destruction of a PRTECTED_DELETE object, it must be added to the static list of PROTECTED_DELETE*
