Macro Definition Documentation

◆ SKIP_OR_ABORT

#define SKIP_OR_ABORT ( errMsg)
Value:
do { \
if (mergeOpts.fErrBehavior == ENTupleMergeErrBehavior::kSkip) { \
Warning("RNTuple::Merge", "Skipping RNTuple due to: %s", (errMsg).c_str()); \
continue; \
} else { \
return R__FAIL(errMsg); \
} \
} while (0)
R__FAIL
#define R__FAIL(msg)
Short-hand to return an RResult<T> in an error state; the RError is implicitly converted into RResult...
Definition RError.hxx:299
TRangeDynCast
ROOT::Detail::TRangeCast< T, true > TRangeDynCast
TRangeDynCast is an adapter class that allows the typed iteration through a TCollection.
Definition TCollection.h:358
