Include dependency graph for RError.hxx:

This graph shows which files directly or indirectly include this file:

Classes
class	ROOT::Experimental::RError
	Captures diagnostics related to a ROOT runtime error. More...
class	ROOT::Experimental::RException
	Base class for all ROOT issued exceptions. More...
struct	ROOT::Experimental::RError::RLocation
class	ROOT::Experimental::RResult< T >
	The class is used as a return type for operations that can fail; wraps a value of type T or an RError. More...
class	ROOT::Experimental::RResult< void >
	RResult<void> has no data member and no Inspect() method but instead a Success() factory method. More...
class	ROOT::Experimental::Internal::RResultBase
	Common handling of the error case for RResult<T> (T != void) and RResult<void> More...

Namespaces
namespace	ROOT
	This file contains a specialised ROOT message handler to test for diagnostic in unit tests.
namespace	ROOT::Experimental
namespace	ROOT::Experimental::Internal

Macros
#define	R__FAIL(msg)   ROOT::Experimental::RError(msg, {R__LOG_PRETTY_FUNCTION, __FILE__, __LINE__})
	Short-hand to return an RResult<T> in an error state; the RError is implicitly converted into RResult<T>
#define	R__FORWARD_ERROR(res)   res.ForwardError(std::move(res), {R__LOG_PRETTY_FUNCTION, __FILE__, __LINE__})
	Short-hand to return an RResult<T> in an error state (i.e. after checking)
#define	R__FORWARD_RESULT(res)   std::move(res.Forward({R__LOG_PRETTY_FUNCTION, __FILE__, __LINE__}))
	Short-hand to return an RResult<T> value from a subroutine to the calling stack frame.
