c++ - Is there an stl container for this hierarchical model data? -

-

for platform-independent model layer, have hierarchical data (strings, actually) this:

  • item
    • subitem a
    • subitem b
    • subitem c
      • subsubitem a
      • subsubitem b
    • subitem d
  • item b
  • item c

now, within each "level" (item, subitem, subsubitem, etc.) items need sorted alphabetically.

seems simple solution create simple class sorted std::vector or std::multimap track children, , pointer parent. (and 1 root item). need iterate through each item's children in forward direction.

after construction/sorting, not need add or delete items. small numbers of items (hundreds).

this model organization of backing data of outline-style control.

rolling simple class easy, such common pattern — isn't there ready-made stl container behavior?

nothing in stl itself, might find useful:

tree.hh: stl-like c++ tree class

its api follows stl containers exactly, , should you're looking for.

i believe their example asking (a tree strings), in fact.
