TMap implements an associative array of (key,value) pairs using a THashTable 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 and the key comparison is done via the IsEqual() function. Both key and value must inherit from TObject.
