A class whose instances match Python regular expressions.
Method Summary
  __init__(self, regex, group, **kwargs)
  __call__(self, parser, origCursor)
  __str__(self)
    Inherited from AbstractToken
  __add__(self, other)
Allows you to construct TokenSequences with the + operator.
  __copy__(self)
  __imod__(self, val)
  __invert__(self)
  __mod__(self, val)
  __mul__(self, val)
Allows you to construct TokenSeries with the * operator.
  __or__(self, other)
Allows you to construct CompositeTokens with the | operator.
  __repr__(self)
  __rmul__(self, val)
Allows you to construct TokenSeries with the * operator.
  __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 |.
  __setattr__(self, name, value)
  __sub__(self, other)
Allows you to construct TokenSequences with the - operator, automatically padded with Whitespace.
  __xor__(self, message)
Overloading for setting the failMessage of a token.

  __new__(T, S, ...)
T.__new__(S, ...) -> a new object with type S, a subtype of T

helper for pickle
  __reduce_ex__(...)

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
NoneType 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.
NoneType to: 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).
