|
|
|
__init__
|
__init__ ( self, listOfCharacters )
Creates an alphabet out of a listOfCharacters
@param listOfCharacters: a list of strings (single characters most of
the time), ints, or other objects that can be used as dictionary keys
for a mapping of the external sequences to the internal representation Note: Alphabets should be considered as imutable. That means the
listOfCharacters and the mapping should never be touched after
construction.

external
|
external ( self, internal )
Given an internal representation return the
external representation Note: the internal code -1 always represents a gap character -
Raises KeyError

Exceptions

KeyError, "Internal symbol " + str( internal ) + " not recognized."

|
|
|
externalSequence
|
externalSequence ( self, internalSequence )
Given a sequence with the internal representation return the
external representation
