Detailed Description

template<typename _Sequence>
class __gnu_debug::_Safe_sequence< _Sequence >

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 const_iterator 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 ( )

protectedinherited

Detach all iterators, leaving them singular.

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

Here is the caller graph for this function:

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 ( )

protectedinherited

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	(
	)

protectedinherited

For use in _Safe_sequence.

void __gnu_debug::_Safe_sequence_base::_M_invalidate_all ( ) const

inlineinherited

Invalidates all iterators.

template<typename _Sequence>

template<typename _Predicate >

void __gnu_debug::_Safe_sequence< _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.

Referenced by __gnu_debug::_Safe_node_sequence< _Sequence >::_M_invalidate_all().

Here is the caller graph for this function:

void __gnu_debug::_Safe_sequence_base::_M_revalidate_singular ( )

protectedinherited

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 )

protectedinherited

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 _Sequence>

template<typename _Predicate >

void __gnu_debug::_Safe_sequence< _Sequence >::_M_transfer_from_if	(	_Safe_sequence< _Sequence > &	__from,
		_Predicate	__pred
	)

Transfers all iterators x that reference from sequence, are not singular, and for which __pred(x) returns true.

__pred will be invoked with the normal iterators nested in the safe ones.
