Member Function Documentation

std::string RepoMetainfoMagicXattr::GetValue ( )

privatevirtual

This function needs to be called after PrepareValueFenced(), which prepares the necessary data. It does the computationaly intensive part, which should not be done inside the FuseRemounter::fence(), and returns the value.

Implements BaseMagicXattr.
