<h3>template<class T><br>
class NLMISC::CSTLBlockAllocator< T ></h3>
This class is a STL block allocator which use <a class="el" href="a02274.html">CBlockMemory</a>. see <a class="el" href="a02274.html">CBlockMemory</a> for description of block memory management/advantages.<p>
This class works with STLPort. It implements __stl_alloc_rebind() (not C++ standard??) to work properly with list<>/set<> etc... node allocations.<p>
NB: if used with a vector<> or a deque<> (ie if allocate(..,n) is called with n>1), it's still work, but it's use malloc()/free() instead, so it is fully unusefull in this case :)<p>
<a class="el" href="a03444.html">CSTLBlockAllocator</a> use a pointer on a <a class="el" href="a02274.html">CBlockMemory</a>, so multiple containers can share the same blockMemory, for maximum space/speed efficiency.<p>
Because of <a class="el" href="a02274.html">CBlockMemory</a> allocation scheme, only same containers of same types can share the same <a class="el" href="a02274.html">CBlockMemory</a> instance (eg: "list<uint, &myBlockMemory>; vector<uint, &myBlockMemory>;" is invalid and will assert when allocations will occur).<p>
To construct a container which use this allocator, do like this: list<uint, CSTLBlockAllocator<uint>> myList( ptrOnBlockMemory );<p>
But see <a class="el" href="a03445.html">CSTLBlockList</a> for easier list instanciation, because using it, you'll do like this: CSTLBlockList<uint> myList(ptrOnBlockMemory);<p>
Note: <a class="el" href="a03444.html">CSTLBlockAllocator</a> take only 4 bytes in memory (a ptr on a <a class="el" href="a02274.html">CBlockMemory</a>)<p>
