[igraph] graph representation in memory: igraph_vector_t

[Mati Vait]

Hello again!

I have a question about igraph_vector_t.


What is the purpose of stor_begin, stor_end, end in igraph_vector_t (it
is defined in vector.h)? 
Following is from vector.h:
 ...
 22 */
 23 
 24 /** 
 25  * Vector, dealing with arrays efficiently.
 26  * \ingroup types
 27  */
 28 
 29 typedef struct TYPE(igraph_vector) {
 30   BASE* stor_begin;
 31   BASE* stor_end;
 32   BASE* end;
 33 } TYPE(igraph_vector);
 34 
 ...

Was there any specific data structure in mind while designing it?


Thank you for your time,
Mati
