Detailed Description

Allocator to customize Value internal map.

Below is an example of a simple implementation (default implementation actually use memory pool for speed).

      class DefaultValueMapAllocator : public ValueMapAllocator
      {
      public: // overridden from ValueMapAllocator
         virtual ValueInternalMap *newMap()
         {
            return new ValueInternalMap();
         }

         virtual ValueInternalMap *newMapCopy( const ValueInternalMap &other )
         {
            return new ValueInternalMap( other );
         }

         virtual void destructMap( ValueInternalMap *map )
         {
            delete map;
         }

         virtual ValueInternalLink *allocateMapBuckets( unsigned int size )
         {
            return new ValueInternalLink[size];
         }

         virtual void releaseMapBuckets( ValueInternalLink *links )
         {
            delete [] links;
         }

         virtual ValueInternalLink *allocateMapLink()
         {
            return new ValueInternalLink();
         }

         virtual void releaseMapLink( ValueInternalLink *link )
         {
            delete link;
         }
      };
