This class generates a map from inputs to integers, where an equivalence class is defined by the trimmer function. It is just a stripped-down version of the hash class defined above. Faster and less memory consumption, if you don't need the rmap method.

Method Details |
x.__init__(...) initializes x; see help(type(x)) for signature
|
Returns an integer which is shared among all x in the equivalence class, but different from all other x. If the trimmer function raises the DontHashThis exception, it will ignore the input and return None.
|
Similar to add, except it returns None if the equivalence class has already appeared.
|
Returns an integer which is shared among all x in the equivalence class, but different from all other x.
Note: the return value is the same as add, except that this doesn't add anything: rather than increasing the size of the mapping, it raises NotInHash. |
Return the map from integers to classes.
