Namespaces

namespace  ROOT
 tbb::task_arena is an alias of tbb::interface7::task_arena, which doesn't allow to forward declare tbb::task_arena without forward declaring tbb::interface7
 
namespace  ROOT::Detail
 Special implementation of ROOT::RRangeCast for TCollection, including a check that the cast target type inherits from TObject and a new constructor that takes the TCollection by pointer.
 
namespace  ROOT::Internal

Typedefs

template<typename T >
using TRangeDynCast = ROOT::Detail::TRangeCast< T, true >

◆ TRangeDynCast

template<typename T >
using TRangeDynCast = ROOT::Detail::TRangeCast<T, true>

TRangeDynCast is an adapter class that allows the typed iteration through a TCollection.

The typical use is:

for(auto bcl : TRangeDynCast<TBaseClass>( *cl->GetListOfBases() )) {
if (!bcl) continue;
... use bcl as a TBaseClass*
}
for(auto bcl : TRangeDynCast<TBaseClass>( cl->GetListOfBases() )) {
if (!bcl) continue;
... use bcl as a TBaseClass*
}
#define a(i)
Definition RSha256.hxx:99
Each class (see TClass) has a linked list of its base class(es).
Definition TBaseClass.h:33
Template Parameters
TThe new type to convert to.
