Class Description

THbookKey(Int_t id, THbookFile *file)
constructor
~THbookKey()


void Browse(TBrowser *b)


 Read object from disk and call its Browse() method.
 If object with same name already exist in memory delete it (like
 TDirectory::Get() is doing), except when the key references a
 folder in which case we don't want to re-read the folder object
 since it might contain new objects not yet saved.



Bool_t IsFolder()


an hbook key is not a folder



 THbookKey()




 THbookKey(Int_t id, THbookFile *file)
