This is a simple, type-safe, and reasonably efficient hash map class,
whose interface is a subset of the interface of STL containers.
In particular, the interface is modeled after std::map, and the various,
- non-standard, std::hash_map.
+ non-standard, std::hash_map (http://www.cppreference.com/wiki/stl/map/start).
Example:
@code
@endcode
The HASH_T and KEY_EQ_T are the types used for the hashing function and
key comparison. wxWidgets provides three predefined hashing functions:
- wxIntegerHash for integer types ( int, long, short, and their unsigned counterparts ),
- wxStringHash for strings ( wxString, wxChar*, char* ), and wxPointerHash for
+ @c wxIntegerHash for integer types ( int, long, short, and their unsigned counterparts ),
+ @c wxStringHash for strings ( wxString, wxChar*, char* ), and @c wxPointerHash for
any kind of pointer.
- Similarly three equality predicates: wxIntegerEqual, wxStringEqual,
- wxPointerEqual are provided.
+ Similarly three equality predicates: @c wxIntegerEqual, @c wxStringEqual,
+ @c wxPointerEqual are provided.
Using this you could declare a hash map mapping int values to wxString like this:
@code
it + 3, it1 - it2.
+ @section hashmap_predef Predefined hashmap types
+
+ wxWidgets defines the following hashmap types:
+ - wxLongToLongHashMap (uses long both for keys and values)
+ - wxStringToStringHashMap (uses wxString both for keys and values)
