Function documentation

TRootSnifferScanRec()

 constructor

~TRootSnifferScanRec()

 destructor

void SetField(const char* name, const char* value)

 record field for current element

void BeforeNextChild()

 indicates that new child for current element will be started

void MakeItemName(const char* objname, TString& itemname)

 constructs item name from object name
 if special symbols like '/', '#', ':', '&', '?',   are used in object name
 they will be replaced with '_'.
 To avoid item name duplication, additional id number can be appended

void CreateNode(const char* _node_name, const char* _obj_name = 0)

 creates new node with specified name
 if special symbols like "[]&<>" are used, node name
 will be replaced by default name like "extra_item_N" and
 original node name will be recorded as "dabc:itemname" field
 Optionally, object name can be recorded as "dabc:realname" field

void CloseNode()

 close started node

void SetRootClass(TClass* cl)

 set root class name as node kind
 in addition, path to master item (streamer info) specified
 Such master item required to correctly unstream data on JavaScript

Bool_t Done()

 returns true if scanning is done
 Can happen when searched element is found

Bool_t SetResult(void* obj, TClass* cl, TDataMember* member = 0, Int_t chlds = -1)

 set results of scanning

Int_t Depth() const

 returns current depth of scanned hierarchy

Int_t ExtraFolderLevel()

 return level depth till folder, marked with extra flag
 Objects in such folder can be 'expanded' -
 one can get access to all class members
 If no extra folder found, -1 is returned

Bool_t CanExpandItem()

 returns true if current item can be expanded - means one could explore
 objects members

Bool_t GoInside(TRootSnifferScanRec& super, TObject* obj, const char* obj_name = 0)

 method verifies if new level of hierarchy should be started with provided
 object
 If required, all necessary nodes and fields will be created
 Used when different collection kinds should be scanned

TRootSnifferScanRec()

Bool_t CanSetFields()

 return true when fields could be set to the hierarchy item
