Detailed Description

The base class for exceptions supported by the Tf exceptions facilities. Typical usage is to publically derive your own exception class from this one, and throw using the TF_THROW() macro.

Deriving this base class and throwing via TF_THROW() will record the throw point's call context (see GetThrowContext()) and will also capture a portion of the throwing thread's call stack (see GetThrowStack()).

Additionally, the Tf library registers an exception translator with boost.python to raise a Python exeption wrapping the thrown exception object. Similarly utilties that call Python via Tf will re-throw the embedded C++ exception if the Python exception unwinds back into C++.

Constructor & Destructor Documentation

virtual TF_API TfBaseException::~TfBaseException ( )

virtual

TF_API TfBaseException::TfBaseException ( std::string const &  message )

explicit

Construct with message, reported by this class's what() implementation.

Member Function Documentation

TfCallContext const& TfBaseException::GetThrowContext ( ) const

inline

Return the call context from the throw point associated with this exception. Note that this context may be invalid if this exception was not thrown with TF_THROW().

Definition at line 60 of file exception.h.

std::vector<uintptr_t> const& TfBaseException::GetThrowStack ( ) const

inline

Return the stack frame pointers from the throw point. See ArchPrintStackFrames() to turn these into human-readable strings.

Definition at line 66 of file exception.h.

void TfBaseException::MoveThrowStackTo ( std::vector< uintptr_t > &  out )

inline

Move the stack frame pointers from the throw point to out. See GetThrowStack() for more details.

Definition at line 72 of file exception.h.

virtual TF_API const char* TfBaseException::what ( ) const

overridevirtualnoexcept

Override std::exception::what() to return the message passed during construction.
