update() [2/4]

void Error::update

(

const ErrorDetailPointer &

detail

)

records an additional error detail (if any), leaving category unchanged more convenient and faster alternative to calling update(Error(ERR_NONE, d))

Parameters

detail

either nil or a pointer to a new or an already known detail

References debugs, details, and ErrorDetail::equals().

update() [3/4]

void Error::update

(

err_type

recentCategory

)

if necessary, stores the given error category (if any), leaving details unchanged; the first non-ERR_NONE category wins; more convenient alternative to calling update(Error(c))
