可能重复:
制作方法在Python子类私有
私有变量和Python中的方法
我如何定义在被保护,只有子类可以看到一个Python类的方法?
这是我的代码:
class BaseType(Model):
def __init__(self):
Model.__init__(self, self.__defaults())
def __defaults(self):
return {'name': {},
'readonly': {},
'constraints': {'value': UniqueMap()},
'cType': {}
}
cType = property(lambda self: self.getAttribute("cType"), lambda self, data: self.setAttribute('cType', data))
name = property(lambda self: self.getAttribute("name"), lambda self, data: self.setAttribute('name', data))
readonly = property(lambda self: self.getAttribute("readonly"),
lambda self, data: self.setAttribute('readonly', data))
constraints = property(lambda self: self.getAttribute("constraints"))
def getJsCode(self):
pass
def getCsCode(self):
pass
def generateCsCode(self, template=None, constraintMap=None, **kwargs):
if not template:
template = self.csTemplate
if not constraintMap: constraintMap = {}
atts = ""
constraintMap.update(constraintMap)
for element in self.getNoneEmptyAttributes():
if not AbstractType.constraintMap.has_key(element[0].lower()):
continue
attTemplate = Template(AbstractType.constraintMap[element[0].lower()]['cs'])
attValue = str(element[1]['value'])
atts += "%s " % attTemplate.substitute({'value': attValue})
kwargs.update(dict(attributes=atts))
return template.substitute(kwargs)
class MainClass(BaseType, Model):
def __init__(self):
#Only Model will initialize
Model.__init__(self, self.__defaults())
BaseType.__init__(self)
def __defaults(self):
return {'name': {},
'fields': {'value': UniqueMap()},
'innerClass': {'value': UniqueMap()},
'types': {}
}
fields = property(lambda self: self.getAttribute("fields"))
innerClass = property(lambda self: self.getAttribute("innerClass"))
types = property(lambda self: self.getAttribute("types"))
@staticmethod
def isType(iType):
# return type(widget) in WidgetSelector.widgets.itervalues()
return isinstance(iType, AbstractType)
def addType(self, type):
if not MainClass.isType(type):
raise Exception, "Unknown widget type %s" % type
self.types[type.name] = type
我想这只是一个子类BaseType
看generateCsCode
的方法BaseType
。
