Detailed Description
Stores a reference to an object's method or a function. This class also provides comparison operators to allow proper usage in containers such as set([]). The ability to change the weak reference is not supported to prevent mutability. This is important for container support as the object hash would change after storing it.
Constructor & Destructor Documentation
◆ __init__()
| def enigma.WeakMethodReference.__init__ | ( | self, | |
function = None |
|||
| ) |
Initialises the weak reference with a function or class method.
Member Function Documentation
◆ __call__()
| def enigma.WeakMethodReference.__call__ | ( | self, | |
| * | args, | ||
| ** | kwargs | ||
| ) |
@return Calls a new bound-method like the original, or the original function if refers just to a function or unbound method and returns its result. Returns None if the original object doesn't exist
◆ __eq__()
| def enigma.WeakMethodReference.__eq__ | ( | self, | |
| other | |||
| ) |
Enables comparison between different weak pointer objects that point to the same object based on the contents instead of the object pointer.
◆ __hash__()
| def enigma.WeakMethodReference.__hash__ | ( | self | ) |
this method is provided to allow comparison of references inside of containers like set([]) http://stackoverflow.com/questions/3942303/how-does-a-python-set-check-if-two-objects-are-equal-what-methods-does-an-o
◆ __ne__()
| def enigma.WeakMethodReference.__ne__ | ( | self, | |
| other | |||
| ) |
Enables comparison between different weak pointer objects that point to the same object based on the contents instead of the object pointer.
◆ is_alive()
| def enigma.WeakMethodReference.is_alive | ( | self | ) |
The equivalent to 'not is_dead()' Make a positive method call because double negatives suck
◆ is_dead()
| def enigma.WeakMethodReference.is_dead | ( | self | ) |
Returns True if the referenced callable was a bound method and the instance no longer exists. Otherwise, return False.
