Part of twisted.python.constants View Source View In Hierarchy
Known subclasses: twisted.positioning.nmea.GPGGAFixQualities, twisted.positioning.nmea.GPGLLGPRMCFixQualities, twisted.positioning.nmea.GPGSAFixTypes, twisted.python.constants.Flags
Values
subclass contains constants which are associated with arbitrary values.Class Method | lookupByValue | Retrieve a constant by its value or raise a ValueError if
there is no constant associated with that value. |
Inherited from _ConstantsContainer:
Method | __new__ | Classes representing constants containers are not intended to be instantiated. |
Class Method | lookupByName | Retrieve a constant by its name or raise a ValueError if
there is no constant associated with that name. |
Class Method | iterconstants | Iteration over a Names subclass
results in all of the constants it contains. |
Class Variable | _constantType | Specified by a _ConstantsContainer
subclass to specify the type of constants allowed by that subclass. |
Class Variable | _enumerants | A dict mapping the names of constants (eg NamedConstant
instances) found in the class definition to those instances. |
Class Method | _constantFactory | Construct the value for a new constant to add to this container. |
ValueError
if
there is no constant associated with that value.Parameters | value | The value of one of the constants defined by cls . |
Returns | The ValueConstant
associated with value . | |
Raises | ValueError | If value is not the value of one of the constants defined by
cls . |
