Description

Description

 
This object is placed in the beginning of memory segment and implements the allocation (named or anonymous) of portions of the segment. This object contains two indexes that maintain an association between a name and a portion of the segment.

 
The first index contains the mappings for normal named objects using the char type specified in the template parameter.

 
The second index contains the association for unique instances. The key will be the const char * returned from type_info.name() function for the unique type to be constructed.

 
segment_manager<CharType, MemoryAlgorithm, IndexType> inherits publicly from segment_manager_base<MemoryAlgorithm> and inherits from it many public functions related to anonymous object and raw memory allocation. See segment_manager_base reference to know about those functions.
