## Class Description

     TMap

     TMap implements an associative array of (key,value) pairs using a
     hash table for efficient retrieval (therefore TMap does not conserve
     the order of the entries). The hash value is calculated
     using the value returned by the keys Hash() function. Both key and
     value need to inherit from TObject.

### Inline Functions

                  TPair TPair(const TPair& a)
                 Bool_t IsFolder() const
                   void Browse(TBrowser* b)
            const char* GetName() const
                ULong_t Hash() const
                 Bool_t IsEqual(const TObject* obj) const
               TObject* Key() const
               TObject* Value() const

                TClass* IsA() const
                   void ShowMembers(TMemberInspector& insp, char* parent)
                   void Streamer(TBuffer& b)
                   void StreamerNVirtual(TBuffer& b)
                 TPair& operator=(const TPair&)
