               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 `TokenSequence`s with the + operator.
	`__or__(self, other)` Allows you to construct `CompositeToken`s 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.

Class Variable Summary
Inherited from AbstractToken
`NoneType`	`failMessage` = None

Method Details

Parameters:: regex - Either a compiled regex object or a string regex.; group - To be set as the object's group property.
(type=int)

Instance Variable Details

If defined, __call__ returns that group of the regular expression match instead of the whole match object.
