class Proxy:
def __init__( self, proxer ):
object.__setattr__( self, '_proxer', proxer )
ComplexObject= object
viewA= type( 'ComplexView', ( Proxy, ComplexObject ), { '__eq__':
lambda self, other: abs( self._proxer- other )<= 1 } )
j= range( 10 )
g= 5
for a in j:
p= viewA( a )
print( p.__class__.__name__, p._proxer, p== g )
Subclassing provides an alternative to delegation and proxying. I got
this far, but I'm lost: How do I allow g= proxy( 5 ) in line 11? Do I
need to?
If I do it, I get:
TypeError line 7: unsupported operand type(s) for -: 'int' and
'ComplexView'
