/** @addtogroup Containers Containers
|
|
Containers are collections of objects.
|
|
|
|
A container may hold any type which meets certain requirements, but the type
|
|
of contained object is chosen at compile time, and all objects in a given
|
|
container must be of the same type. (Polymorphism is possible by declaring a
|
|
container of pointers to a base class and then populating it with pointers to
|
|
instances of derived classes. Variant value types such as the @c any class
|
|
from <a href="http://www.boost.org/">Boost</a> can also be used.
|
|
|
|
All contained types must be @c Assignable and @c CopyConstructible.
|
|
Specific containers may place additional requirements on the types of
|
|
their contained objects.
|
|
|
|
Containers manage memory allocation and deallocation themselves when
|
|
storing your objects. The objects are destroyed when the container is
|
|
itself destroyed. Note that if you are storing pointers in a container,
|
|
@c delete is @e not automatically called on the pointers before destroying them.
|
|
|
|
All containers must meet certain requirements, summarized in
|
|
<a href="tables.html">tables</a>.
|
|
|
|
The standard containers are further refined into
|
|
@link Sequences Sequences@endlink and
|
|
@link Assoc_containers Associative Containers@endlink.
|
|
*/
|
|
|
|
/** @addtogroup Sequences Sequences
|
|
Sequences arrange a collection of objects into a strictly linear order.
|
|
|
|
The differences between sequences are usually due to one or both of the
|
|
following:
|
|
- memory management
|
|
- algorithmic complexity
|
|
|
|
As an example of the first case, @c vector is required to use a contiguous
|
|
memory layout, while other sequences such as @c deque are not.
|
|
|
|
The prime reason for choosing one sequence over another should be based on
|
|
the second category of differences, algorithmic complexity. For example, if
|
|
you need to perform many inserts and removals from the middle of a sequence,
|
|
@c list would be ideal. But if you need to perform constant-time access to
|
|
random elements of the sequence, then @c list should not be used.
|
|
|
|
All sequences must meet certain requirements, summarized in
|
|
<a href="tables.html">tables</a>.

*/
|
|
|
|
/** @addtogroup Assoc_containers Associative Containers
|
|
Associative containers allow fast retrieval of data based on keys.
|
|
|
|
Each container type is parameterized on a @c Key type, and an ordering
|
|
relation used to sort the elements of the container.
|
|
|
|
There should be more text here.

|

|
|
* along with the current specification.
|
|
*
|
|
* For users of GCC 3.x, entry points are available in <cxxabi.h>, which notes,

@param mangled_name A NUL-terminated character string containing the name

|
|
|
|
@param output_buffer A region of memory, allocated with malloc, of
|
|
@a *length bytes, into which the demangled name
|
|
is stored. If @a output_buffer is not long enough,
|
|
it is expanded using realloc. @a output_buffer may
|
|
instead be NULL; in that case, the demangled name is
|
|
placed in a region of memory allocated with malloc.
|
|
|
|
@param length If @a length is non-NULL, the length of the buffer containing
|
|
the demangled name is placed in @a *length.
|
|
|
|
@param status @a *status is set to one of the following values:
|
|
- 0: The demangling operation succeeded.
|
|
- -1: A memory allocation failiure occurred.
|
|
- -2: @a mangled_name is not a valid name under the C++ ABI
|
|
mangling rules.
|
|
- -3: One of the arguments is invalid.
|
|
|
|
@return A pointer to the start of the NUL-terminated demangled name, or NULL
|
|
if the demangling fails. The caller is responsible for deallocating
|
|
this memory using @c free.
|
|
|
|
|
|
The demagling is performed using the C++ ABI mangling rules, with
|
|
GNU extensions. For example, this function is used
|
|
in __gnu_cxx::__verbose_terminate_handler. See
|
|
http://gcc.gnu.org/onlinedocs/libstdc++/18_support/howto.html#5 for other
|
|
examples of use.
|
|
|
|
@note The same demangling functionality is available via libiberty
|
|
(@c <libiberty/demangle.h> and @c libiberty.a) in GCC 3.1 and later, but that
|
|
requires explicit installation (@c --enable-install-libiberty) and uses a
|
|
different API, although the ABI is unchanged.

/** @addtogroup binarysearch Binary search algorithms
|
|
These algorithms are variations of a classic binary search. They all assume
|
|
that the sequence being searched is already sorted.
|
|
|
|
The number of comparisons will be logarithmic (and as few as possible).
|
|
The number of steps through the sequence will be logarithmic for
|
|
random-access iterators (e.g., pointers), and linear otherwise.
|
|
|
|
The LWG has passed Defect Report 270, which notes: <em>The proposed
|
|
resolution reinterprets binary search. Instead of thinking about searching
|
|
for a value in a sorted range, we view that as an important special
|
|
case of a more general algorithm: searching for the partition point in a
|
|
partitioned range. We also add a guarantee that the old wording did not:
|
|
we ensure that the upper bound is no earlier than the lower bound, that
|
|
the pair returned by equal_range is a valid range, and that the first part
|
|
of that pair is the lower bound.</em>
|
|
|
|
The actual effect of the first sentence is that a comparison functor
|
|
passed by the user doesn't necessarily need to induce a strict weak ordering
|
|
relation. Rather, it partitions the range.
