This just provides documentation for stuff that doesn't need to be in the
|
|
source headers themselves. It is a ".cc" file for the sole cheesy reason
|
|
that it triggers many different text editors into doing Nice Things when
|
|
typing comments. However, it is mentioned nowhere except the *cfg.in files.
|
|
|
|
Some actual code (declarations) is exposed here, but no compiler ever
|
|
sees it. The decls must be visible to doxygen, and sometimes their real
|
|
declarations are not visible, or not visible in a way we want.
|

Pieces separated by '// //' lines will usually not be presented to the

user on the same page.

Because libstdc++ based its implementation of the STL subsections of
|
|
the library on the SGI 3.3 implementation, we inherited their extensions
|
|
as well.
|
|
|
|
They are additionally documented in the
|
|
<a href="http://gcc.gnu.org/onlinedocs/libstdc++/documentation.html">
|
|
online documentation</a>, a copy of which is also shipped with the
|
|
library source code (in .../docs/html/documentation.html). You can also
|
|
read the documentation <a href="http://www.sgi.com/tech/stl/">on SGI's
|
|
site</a>, which is still running even though the code is not maintained.
|
|
|
|
<strong>NB</strong> that the following notes are pulled from various
|
|
comments all over the place, so they may seem stilted.

/** @defgroup 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 associative_containers Associative Containers@endlink.
|
|
@link unordered_associative_containers Unordered Associative Containers@endlink.

|
/** @defgroup sequences Sequences
|
|
* @ingroup containers
|
|
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>.

Associative containers allow fast retrieval of data based on keys.
