Detailed Description

Basic functionality for a safe iterator.

The _Safe_local_iterator_base base class implements the functionality of a safe local iterator that is not specific to a particular iterator type. It contains a pointer back to the container it references along with iterator version information and pointers to form a doubly-linked list of local iterators referenced by the container.

This class must not perform any operations that can throw an exception, or the exception guarantees of derived iterators will be broken.

Constructor & Destructor Documentation

__gnu_debug::_Safe_local_iterator_base::_Safe_local_iterator_base ( )

inlineprotected

Initializes the iterator and makes it singular.

    { }

__gnu_debug::_Safe_local_iterator_base::_Safe_local_iterator_base ( const _Safe_sequence_base *  __seq, bool  __constant  )

inlineprotected

Initialize the iterator to reference the container pointed to by __seq. __constant is true when we are initializing a constant local iterator, and false if it is a mutable local iterator. Note that __seq may be NULL, in which case the iterator will be singular. Otherwise, the iterator will reference __seq and be nonsingular.

    { this->_M_attach(const_cast<_Safe_sequence_base*>(__seq), __constant); }

__gnu_debug::_Safe_local_iterator_base::_Safe_local_iterator_base ( const _Safe_local_iterator_base &  __x, bool  __constant  )

inlineprotected

Initializes the iterator to reference the same container that __x does. __constant is true if this is a constant iterator, and false if it is mutable.

    { this->_M_attach(__x._M_sequence, __constant); }

Member Function Documentation

void __gnu_debug::_Safe_local_iterator_base::_M_attach	(	_Safe_sequence_base *	__seq,
		bool	__constant
	)

Attaches this iterator to the given container, detaching it from whatever container it was attached to originally. If the new container is the NULL pointer, the iterator is left unattached.

void __gnu_debug::_Safe_local_iterator_base::_M_attach_single	(	_Safe_sequence_base *	__seq,
		bool	__constant
	)
throw	(
	)

Likewise, but not thread-safe.

void __gnu_debug::_Safe_local_iterator_base::_M_detach

(

)

Detach the iterator for whatever container it is attached to, if any.

void __gnu_debug::_Safe_local_iterator_base::_M_detach_single	(		)
throw	(
	)

Likewise, but not thread-safe.
