bimap

First part of the question is that I am trying to use boost::bimap, but from the documentation it is unclear to me how to define a bidirectional multimap. The second part of the question is that I need it to be a map in one direction and a multimap in the other direction, can this be done using boost::bimap ? Has anyone experience of this or can point me to the correct page ? ForEveR All is in documentation... http://www.boost.org/doc/libs/1_51_0/libs/bimap/doc/html/boost_bimap/the_tutorial/discovering_the_bimap_framework.html typedef boost::bimap<bimaps::multiset_of<int>, bimaps::set_of<int>>

I'm using Eclipse, and I've added google-collect.1.0-rc2.jar as a referenced library. Yet somehow this still doesn't work: import com.google.common.collect.HashBiMap; public class Odp { //... HashBiMap<Character, Integer> charOcc = HashBiMap<Character, Integer>.create(); } Eclipse gives the following errors: Multiple markers at this line HashBiMap cannot be resolved Character.Integer cannot be resolved Syntax error on token ",", "." expected Syntax error on token ".", delete this token The method create() is undefined for class Odp What am I doing wrong? Other Google stuff, like Joiner, works

Short question: Can I typedef a variadic argument pack? I need template <typename ...T> struct Forward { typedef T... args; }; . Long version: I was thinking about reimplementing the excellent boost bimap in C++0x. Recall that a bimap of two types S and T is a std::set of relations between S x and T y . The objects themselves are stored in two independent internal containers, and the relations track the associated iterators I suppose; both types can serve as keys via "left" and "right" lookup. Depending on the choice of internal containers, values may be unique or not, e.g. if the left

I currently face the problem of java.lang.NoClassDefFoundError: com.google.common.collect.HashBiMap when using guava libraries downloaded from here: http://code.google.com/p/guava-libraries/ I already add guava-12.0.jar into my project as a reference library but I still get the error. May you give some advice on what the problem would be? Thankyou for your help package my.project; import android.app.Activity; import android.os.Bundle; import com.google.common.collect.BiMap; import com.google.common.collect.HashBiMap; public class MainActivity extends Activity{ private BiMap<String,String>

As we now, there is the concept of BiMap and multiMap but is there a multiBiMap ? so what do I mean by this. In multiMap you have one-to-many relationship between K and V, a single key can be associated to multiple value, hence the name. In bi map you have K,V pair which is bi-directional mean you can get V,K relationship as well. Like having a two regular maps but synchronized. I need a bi directional multi map where you combine these two concepts. import java.util.Set; import com.google.common.collect.HashMultimap; import com.google.common.collect.SetMultimap; public class ManyToMany<K, V> {

Is there a usable alternative to Boost's bimap in C++0x? I would like to avoid Boost, but fully embrace C++11. If necessary, a slimmed down version of Boost's bimap would work for me (I need a constant bimap to switch between enums and corresponding strings) throughout my program. The map will be compile-time constant, so perhaps even two manually maintained maps aren't the optimal solution. Thanks! UPDATE: I found this on The Code Project, but it seems licensing may be an issue: http://www.codeproject.com/KB/stl/bimap.aspx?fid=12042&df=90&mpp=25&noise=3&sort=Position&view=Quick&fr=151#xx0xx I
