Constructor & Destructor Documentation

JROOT::JRootDictionary::JRootDictionary ( )

inline

Default constructor.

This constructor builds a default dictionary which includes all primitive data types and std::vector thereof.

Removed types:

• long double (not supported by ROOT TDictionary)

Added ROOT type definitions:

• std::string
• [U]Char_t
• [U]Short_t
• [U]Int_t
• [U]Long64_t
• [U]Float_t
• [U]Double_t
