Member Function Documentation

◆ AccessObject()

virtual void * ROOT::Experimental::Browsable::RHolder::AccessObject ( )
inlineprotectedvirtual

Returns plain object pointer without care about ownership, should not be used often.

Reimplemented in ROOT::Experimental::Browsable::RAnyObjectHolder, and ROOT::Experimental::Browsable::TObjectHolder.

Definition at line 43 of file RHolder.hxx.

template<class T >
bool ROOT::Experimental::Browsable::RHolder::CanCastTo ( ) const
inline

Definition at line 64 of file RHolder.hxx.

◆ Copy()

auto ROOT::Experimental::Browsable::RHolder::Copy ( ) const

Returns plains pointer on object without ownership, only can be used for TObjects.

Definition at line 118 of file RHolder.hxx.

◆ get_shared()

template<class T >
std::shared_ptr< T > ROOT::Experimental::Browsable::RHolder::get_shared ( )
inline
