twisted.python.constants : API documentation

Symbolic constant support, including collections and constants with text, numeric, and bit flag values.

Class	NamedConstant	`NamedConstant` defines an attribute to be a named constant within a collection defined by a `Names` subclass.
Class	Names	A `Names` subclass contains constants which differ only in their names and identities.
Class	ValueConstant	`ValueConstant` defines an attribute to be a named constant within a collection defined by a `Values` subclass.
Class	Values	A `Values` subclass contains constants which are associated with arbitrary values.
Class	FlagConstant	`FlagConstant` defines an attribute to be a flag constant within a collection defined by a `Flags` subclass.
Class	Flags	A `Flags` subclass contains constants which can be combined using the common bitwise operators (`\|`, `&`, etc) similar to a bitvector from a language like C.
Class	_Constant
Class	_ConstantsContainerType	`_ConstantsContainerType` is a metaclass for creating constants container classes.
Class	_ConstantsContainer	`_ConstantsContainer` is a class with attributes used as symbolic constants. It is up to subclasses to specify what kind of constants are allowed.
Function	_flagOp	Implement a binary operator for a `FlagConstant` instance.

def _flagOp(op, left, right): (source)

Implement a binary operator for a FlagConstant instance.

Parameters	op	A two-argument callable implementing the binary operation. For example, `operator.or_`.
	left	The left-hand `FlagConstant` instance.
	right	The right-hand `FlagConstant` instance.
Returns	A new `FlagConstant` instance representing the result of the operation.
