How to wrap every method of a class? [duplicate]

Answer 1

You mean programatically set a wrapper to methods of a class?? Well, this is probably a really bad practice, but here's how you may do it:

def wrap_methods( cls, wrapper ):
    for key, value in cls.__dict__.items( ):
        if hasattr( value, '__call__' ):
            setattr( cls, key, wrapper( value ) )

If you have class, for example

class Test( ):
    def fire( self ):
        return True
    def fire2( self ):
        return True

and a wrapper

def wrapper( fn ):
    def result( *args, **kwargs ):
        print 'TEST'
        return fn( *args, **kwargs )
    return result

then calling

wrap_methods( Test, wrapper )

will apply wrapper to all methods defined in class Test. Use with caution! Actually, don't use it at all!
