TCEVersionString()

std::string Application::TCEVersionString ( )

static

Returns the version string of the TCE build.

This string includes the version control revision (if available), automatically generated during build. This cannot be in headers as it would induce a (almost) complete build of TCE on every revision change.

warningStream()

std::ostream & Application::warningStream ( )
