               Token


A class whose instances match Python regular expressions.
Method Summary
  __init__(self, regex, callback, as, name, group)
  __call__(self, parser, origCursor)
  __str__(self)
    Inherited from AbstractToken
  __add__(self, other)
Allows you to construct TokenSequences with the + operator.
  __or__(self, other)
Allows you to construct CompositeTokens with the | operator.
  __repr__(self)
  __rshift__(self, callback)
Convenience overloading for setting the callback of a token whose initializer you do not call directly, such as the result of combining tokens with + or |.
  __xor__(self, message)
Overloading for setting the failMessage of a token.
  preprocessResult(self, parser, data, origCursor)
Method called by subclasses' __call__ methods to add uniform support for the callback and as parameters.

Instance Variable Summary
int group: If defined, __call__ returns that group of the regular expression match instead of the whole match object.
    Inherited from AbstractToken
  as: An optional callable which, if not None, will be called in the same manner as a callback (after any callback and before returning to the parser instance), but will be passed only one argument: the data matched (or returned by the callback, if any).
  callback: An optional callable which, if not None, will be called whenever an instance matches successfully.
  desc: The generic "description" variable which stores the "essence" of any given instance.
