This is a way to declare something about a class definition, similar to L{zope.interface.implementer}. Use it like this:: magic = Expose('perform extra magic') class Foo(Bar): def twiddle(self, x, y): ... def frob(self, a, b): ... magic(twiddle, frob) Later you can query the object:: aFoo = Foo() magic.get(aFoo, 'twiddle')(x=1, y=2) The call to C{get} will fail if the name it is given has not been exposed using C{magic}. @param funcObjs: One or more function objects which will be exposed to the client. @return: The first of C{funcObjs}. z,expose() takes at least 1 argument (0 given)�exposedThroughr )� TypeError�getattr�append�setattr)�selfr �fObjr � r �6/usr/lib/python3/dist-packages/twisted/web/_element.py�__call__"
