ROOT 6.10/09 Reference Guide |
This class stores a (key,value) pair using an external hash.
The (key,value) are Long64_t's and therefore can contain object pointers or any longs. The map uses an open addressing hashing method (linear probing).

Return the value belonging to specified key and hash value.
If key not found return 0. In 'slot', return the index of the slot used or the first empty slot. (to be used with AddAt).
Definition at line 196 of file TExMap.cxx.
Return a reference to the value belonging to the key with the specified hash value.
If the key does not exist it will be added. NOTE: the reference will be invalidated an Expand() triggered by an Add() or another operator() call.
