It is object of the class A, in conteiner's class tmpA. Not all method
from A are in the tmpA. So for exapmle:
A + B -- yes , tmpA + B no. I try to call method from A for tmpA. I
can to call simple method, such as change(), bit __add__ - don't
work. If to remove inheritance from object, the code work's. Help me,
please
#--------------------------------------
class A(object):
def __init__( self, x, y ):
self.x = x
self.y = y
pass
#-------
def __add__( self, arg ):
tmp1 = self.x + arg.x
tmp2 = self.y + arg.y
return tmpA( A( tmp1, tmp2 ) )
def change( self, x, y ):
self.x = x
self.y = y
pass
pass
#------------------------------------------
class tmpA( object ):
def __init__( self, theA ):
self.A = theA
pass
#-------
def __call__( self ):
return self.A
#-------
def __coerce__( self, *args ):
return None
#-------
def __getattr__( self, *args ):
name = args[ 0 ]
try:
attr = None
exec "attr = self.__call__().%s" % name
return attr
except :
raise AttributeError
#--------------------------------------
class B( object ):
def __init__( self, x, y):
self.x = x
self.y = y
pass
#-------------------------------------
a=A( 1,2 )
b=B( 3,4 )
tmp_a = a + b #well
tmp_a.change( 0, 0 ) # very well !!!
v = tmp_a + b #TypeError: "unsupported operand type(s) for +: 'tmpA'
and 'B'"
