Bool_t REveManager::InsertVizDBEntry ( const TString tag,
REveElement model,
Bool_t  replace,

Insert a new visualization-parameter database entry.

Returns true if the element is inserted successfully. If entry with the same key already exists the behaviour depends on the 'replace' flag:

  • true - The old model is deleted and new one is inserted (default). Clients of the old model are transferred to the new one and if 'update' flag is true (default), the new model's parameters are assigned to all clients.
  • false - The old model is kept, false is returned.

If insert is successful, the ownership of the model-element is transferred to the manager.
