The no-throw guarantee holds only, if the VoidOrKeyEqual object and Hasher don't throw.</para><para>hashtable is a semi-intrusive container: each object to be stored in the container must contain a proper hook, but the container also needs additional auxiliary memory to work: hashtable needs a pointer to an array of type <computeroutput>bucket_type</computeroutput> to be passed in the constructor. This bucket array must have at least the same lifetime as the container. This makes the use of hashtable more complicated than purely intrusive containers. <computeroutput>bucket_type</computeroutput> is default-constructible, copyable and assignable</para><para>The template parameter <computeroutput>T</computeroutput> is the type to be managed by the container. The user can specify additional options and if no options are provided default options are used.</para><para>The container supports the following options: <computeroutput>base_hook&lt;&gt;/member_hook&lt;&gt;/value_traits&lt;&gt;</computeroutput>, <computeroutput>constant_time_size&lt;&gt;</computeroutput>, <computeroutput>size_type&lt;&gt;</computeroutput>, <computeroutput>hash&lt;&gt;</computeroutput> and <computeroutput>equal&lt;&gt;</computeroutput> <computeroutput>bucket_traits&lt;&gt;</computeroutput>, power_2_buckets&lt;&gt;, cache_begin&lt;&gt; and incremental&lt;&gt;.</para><para>hashtable only provides forward iterators but it provides 4 iterator types: iterator and const_iterator to navigate through the whole container and local_iterator and const_local_iterator to navigate through the values stored in a single bucket. Local iterators are faster and smaller.</para><para>It's not recommended to use non constant-time size hashtables because several key functions, like "empty()", become non-constant time functions. Non constant_time size hashtables are mainly provided to support auto-unlink hooks.</para><para>hashtables, does not make automatic rehashings nor offers functions related to a load factor. Rehashing can be explicitly requested and the user must provide a new bucket array that will be used from that moment.</para><para>Since no automatic rehashing is done, iterators are never invalidated when inserting or erasing elements. Iterators are only invalidated when rehashing. </para></description><typedef name="value_traits"><type>ValueTraits</type></typedef>

    </template><description><para>The class template slist is an intrusive container, that encapsulates a singly-linked list. You can use such a list to squeeze the last bit of performance from your application. Unfortunately, the little gains come with some huge drawbacks. A lot of member functions can't be implemented as efficiently as for standard containers. To overcome this limitation some other member functions with rather unusual semantics have to be introduced.</para><para>The template parameter <computeroutput>T</computeroutput> is the type to be managed by the container. The user can specify additional options and if no options are provided default options are used.</para><para>The container supports the following options: <computeroutput>base_hook&lt;&gt;/member_hook&lt;&gt;/value_traits&lt;&gt;</computeroutput>, <computeroutput>constant_time_size&lt;&gt;</computeroutput>, <computeroutput>size_type&lt;&gt;</computeroutput>, <computeroutput>linear&lt;&gt;</computeroutput> and <computeroutput>cache_last&lt;&gt;</computeroutput>.</para><para>The iterators of slist are forward iterators. slist provides a static function called "previous" to compute the previous iterator of a given iterator. This function has linear complexity. To improve the usability esp. with the '*_after' functions, ++end() == begin() and previous(begin()) == end() are defined. An new special function "before_begin()" is defined, which returns an iterator that points one less the beginning of the list: ++before_begin() == begin() </para></description><typedef name="value_traits"><type>ValueTraits</type></typedef>
