[Xen-devel] about Xen API's 'api' attribute

["Yanjun Wu" <yanjun.wu@xxxxxxxxx>]

when reading the following code, the line marked with * calls
hasattr(meth, 'api').
But I cannot find where 'api' attribute is set to the method after
searching the whole directory.
And also, what kind of typical methods are in self.xenapi? I traced to
Unix PAM, then get stucked.  thanks.

================
tools/python/xen/xend/server/XMLRPCServer.py : line 171
----------------
        # Register Xen API Functions
        # exportable functions are ones that do not begin with '_'
        # and has the 'api' attribute.

        for meth_name in dir(self.xenapi):
            if meth_name[0] != '_':
                meth = getattr(self.xenapi, meth_name)
   *            if callable(meth) and hasattr(meth, 'api'):
                    self.server.register_function(meth, getattr(meth,
'api'))
