| Method called when new childs are add or old are removed. More... | |
| virtual bool | _DoDeleteItself () |
| This method is called at the moment when DecReference think that object can be destroyed and wants to return true. More... | |
| bool | _IsNormalState () |
| Same as IsNormalState() but without mutex lock - user should lock mutex himself. More... | |

| Method used to create new item to be placed as child of the object. More... | |
| void | DeleteThis () |
| Method should be used by the object to delete itself. More... | |
| bool | DestroyCalledFromOwnThread () |
| Internal DABC method, should be called by thread which was requested to destroy object. More... | |
| void | FillFullName (std::string &fullname, Object *upto, bool exclude_top_parent=false) const |
| Method used to produce full item name,. More... | |
| bool | GetFlag (unsigned fl) const |
| Return value of selected flag, not thread safe More... | |
| bool | IsNormalState () |
| Return true if object is in normal state. More... | |
| unsigned | NumReferences () |
| Return number of references on the object. More... | |
| Object (const ConstructorPair &pair, unsigned flags=flIsOwner) | |
| Mutex * | ObjectMutex () const |
| Returns mutex, used for protection of Object data members. More... | |
| void | SetAutoDestroy (bool on=true) |
| Set autodestroy flag for the object Once enabled, object will be destroyed when last reference will be cleared. More... | |
| void | SetFlag (unsigned fl, bool on=true) |
| Change value of selected flag, not thread safe More... | |
| void | SetName (const char *name) |
| Changes object name. More... | |
| void | SetNameDirect (const char *name) |
| Changes object name disregard of existing references. More... | |
