ROOT::Internal::RStringPool Class Reference

Used for string interning of repeated type names, field names, etc.

The call operator returns for every given string the one immutable pointer to that string in the pool. After calling Freeze(), no new string must be added and the pool is safe to use from multiple threads.

Freeze()

void ROOT::Internal::RStringPool::Freeze ( )

inline

Intern()

const std::string * ROOT::Internal::RStringPool::Intern

(

std::string_view

str

)

Searches for str in the pool.

If not present, adds the string to the pool before returning a pointer to it. Throws if frozen and str is not yet in the pool.
