~Safe_iterator_base () |
The Safe_iterator_base base class implements the functionality of a safe iterator that is not specific to a particular iterator type. It contains a pointer back to the sequence it references along with iterator version information and pointers to form a doubly-linked list of 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.

__gnu_debug::Safe_iterator_base::Safe_iterator_base | ( | ) | [inline, protected] |
Initializes the iterator and makes it singular.

__gnu_debug::Safe_iterator_base::Safe_iterator_base | ( | const Safe_sequence_base * | seq, | |
bool | constant | |||
) | [inline, protected] |
Initialize the iterator to reference the sequence pointed to by . constant
is true when we are initializing a constant iterator, and false if it is a mutable iterator. Note that seq
may be NULL, in which case the iterator will be singular. Otherwise, the iterator will reference seq
and be nonsingular.

__gnu_debug::Safe_iterator_base::Safe_iterator_base | ( | const Safe_iterator_base & | x, | |
bool | constant | |||
) | [inline, protected] |
Initializes the iterator to reference the same sequence that x
does. constant
is true if this is a constant iterator, and false if it is mutable.

bool __gnu_debug::Safe_iterator_base::M_attached_to | ( | const Safe_sequence_base * | seq | ) | const [inline] |
Determines if we are attached to the given sequence.

void __gnu_debug::Safe_iterator_base::M_detach | ( | ) |
bool __gnu_debug::Safe_iterator_base::M_singular | ( | ) | const |
Pointer to the next iterator in the sequence's list of iterators. Only valid when M_sequence != NULL.
Definition at line 72 of file safe_base.h.
Pointer to the previous iterator in the sequence's list of iterators. Only valid when M_sequence != NULL.
Definition at line 68 of file safe_base.h.
The sequence this iterator references; may be NULL to indicate a singular iterator.
Definition at line 55 of file safe_base.h.
unsigned int __gnu_debug::Safe_iterator_base::M_version |
The version number of this iterator. The sentinel value 0 is used to indicate an invalidated iterator (i.e., one that is singular because of an operation on the container). This version number must equal the version number in the sequence referenced by M_sequence for the iterator to be non-singular.
