Template Parameters

InfoType

ExceptionInfo type to get the value for.

Todo:

The added information is currently not accessible through what(), nor through any other means except for calling printFatalErrorMessage(), formatExceptionMessageToString() or formatExceptionMessageToFile(). See ExceptionInitializer for more discussion.

template<class Tag , typename T >

void gmx::GromacsException::setInfo ( const ExceptionInfo< Tag, T > &  item )

inline

Associates extra information with the exception.

Template Parameters

Tag	ExceptionInfo tag type.
T	ExceptionInfo value type.

Parameters

[in]

item

ExceptionInfo to associate.

Exceptions

std::bad_alloc	if out of memory.

If an item of this type is already associated, it is overwritten.

const char * gmx::GromacsException::what ( ) const

overridenoexcept
