Detailed Description

Base class for constructing a safe sequence type that tracks iterators that reference it.

The class template _Safe_sequence simplifies the construction of safe sequences that track the iterators that reference the sequence, so that the iterators are notified of changes in the sequence that may affect their operation, e.g., if the container invalidates its iterators or is destructed. This class template may only be used by deriving from it and passing the name of the derived class as its template parameter via the curiously recurring template pattern. The derived class must have iterator and types that are instantiations of class template _Safe_iterator for this sequence. Iterators will then be tracked automatically.


Member Function Documentation

void __gnu_debug::_Safe_sequence_base::_M_attach ( _Safe_iterator_base __it,
bool  __constant 
) [inherited]

Attach an iterator to this sequence.

void __gnu_debug::_Safe_sequence_base::_M_attach_single ( _Safe_iterator_base __it,
bool  __constant 
) throw () [inherited]

Likewise but not thread safe.

void __gnu_debug::_Safe_sequence_base::_M_detach ( _Safe_iterator_base __it) [inherited]

Detach an iterator from this sequence

void __gnu_debug::_Safe_sequence_base::_M_detach_all ( ) [protected, inherited]

Detach all iterators, leaving them singular.

Referenced by __gnu_debug::_Safe_sequence_base::~_Safe_sequence_base().

void __gnu_debug::_Safe_sequence_base::_M_detach_single ( _Safe_iterator_base __it) throw () [inherited]

Likewise but not thread safe.

void __gnu_debug::_Safe_sequence_base::_M_detach_singular ( ) [protected, inherited]

Detach all singular iterators.

Postcondition:
for all iterators i attached to this sequence, i->_M_version == _M_version.
__gnu_cxx::__mutex& __gnu_debug::_Safe_sequence_base::_M_get_mutex ( ) throw () [protected, inherited]

For use in _Safe_sequence.

Referenced by _M_transfer_from_if().

void __gnu_debug::_Safe_sequence_base::_M_invalidate_all ( ) const [inline, inherited]

Invalidates all iterators.

Definition at line 234 of file safe_base.h.

References __gnu_debug::_Safe_sequence_base::_M_version.

template<typename _Predicate >
void __gnu_debug::_Safe_sequence::_M_invalidate_if ( _Predicate  __pred)

Invalidates all iterators x that reference this sequence, are not singular, and for which pred(x) returns true. pred will be invoked with the normal iterators nested in the safe ones.

Definition at line 38 of file safe_sequence.tcc.

void __gnu_debug::_Safe_sequence_base::_M_revalidate_singular ( ) [protected, inherited]

Revalidates all attached singular iterators. This method may be used to validate iterators that were invalidated before (but for some reason, such as an exception, need to become valid again).

void __gnu_debug::_Safe_sequence_base::_M_swap ( _Safe_sequence_base __x) [protected, inherited]

Swap this sequence with the given sequence. This operation also swaps ownership of the iterators, so that when the operation is complete all iterators that originally referenced one container now reference the other container.

template<typename _Predicate >
void __gnu_debug::_Safe_sequence::_M_transfer_from_if ( _Safe_sequence __from,
_Predicate  __pred 
)
