我们从Python开源项目中，提取了以下15个代码示例，用于说明如何使用symbol.decorators()。
def decorators(self, nodelist): # decorators: decorator ([NEWLINE] decorator)* NEWLINE items = [] for dec_nodelist in nodelist: assert dec_nodelist[0] == symbol.decorator items.append(self.decorator(dec_nodelist[1:])) return Decorators(items)
def decorated(self, nodelist): assert nodelist[0][0] == symbol.decorators if nodelist[1][0] == symbol.funcdef: n = [nodelist[0]] + list(nodelist[1][1:]) return self.funcdef(n) elif nodelist[1][0] == symbol.classdef: decorators = self.decorators(nodelist[0][1:]) cls = self.classdef(nodelist[1][1:]) cls.decorators = decorators return cls raise WalkerError()
def funcdef(self, nodelist): # -6 -5 -4 -3 -2 -1 # funcdef: [decorators] 'def' NAME parameters ':' suite # parameters: '(' [varargslist] ')' if len(nodelist) == 6: assert nodelist[0][0] == symbol.decorators decorators = self.decorators(nodelist[0][1:]) else: assert len(nodelist) == 5 decorators = None lineno = nodelist[-4][2] name = nodelist[-4][1] args = nodelist[-3][2] if args[0] == symbol.varargslist: names, defaults, flags = self.com_arglist(args[1:]) else: names = defaults = () flags = 0 doc = self.get_docstring(nodelist[-1]) # code for function code = self.com_node(nodelist[-1]) if doc is not None: assert isinstance(code, Stmt) assert isinstance(code.nodes[0], Discard) del code.nodes[0] return Function(decorators, name, names, defaults, flags, doc, code, lineno=lineno)
