I’m not entirely sure of what you mean by the ‘current objects’. You can iterate over ObjectSpace, as has been mentioned already. But here are a few other methods. local_variables instance_variables global_variables class_variables constants There’s one gotcha. They must be called at the right scopes. So right in IRB, or in an object instance or … Read more
I’m surprised that this question is so old and no one has taken the time to add the actual introspective way to do this, so here it is: The code you want to inspect… def template(func): def wrapper(*args, **kwargs): return func(*args, **kwargs) return wrapper baz = template che = template class Foo(object): @baz @che def … Read more
Below is the hard way. Here’s the easy way. Don’t know why it didn’t occur to me sooner. import inspect def get_user_attributes(cls): boring = dir(type(‘dummy’, (object,), {})) return [item for item in inspect.getmembers(cls) if item[0] not in boring] Here’s a start def get_user_attributes(cls): boring = dir(type(‘dummy’, (object,), {})) attrs = {} bases = reversed(inspect.getmro(cls)) for … Read more
Have a look at Obtaining Field Types from the Java Tutorial Trail: The Reflection API. Basically, what you need to do is to get all java.lang.reflect.Field of your class and call Field#getType() on each of them (check edit below). To get all object fields including public, protected, package and private access fields, simply use Class.getDeclaredFields(). … Read more
It signifies the end of the positional only parameters, parameters you cannot use as keyword parameters. Before Python 3.8, such parameters could only be specified in the C API. It means the key argument to __contains__ can only be passed in by position (range(5).__contains__(3)), not as a keyword argument (range(5).__contains__(key=3)), something you can do with … Read more
There are (rather too) many ways to do this in Perl because there are so many ways to do things in Perl. As someone commented, autoloaded methods will always be a bit tricky. However, rather than rolling your own approach I would suggest that you take a look at Class::Inspector on CPAN. That will let … Read more
In addition to Buzzy’s answer, for debugging purposes you may use the -[NSObject _methodDescription] private method. Either in lldb: (lldb) po [[UIApplication sharedApplication] _methodDescription] or in code: @interface NSObject (Private) – (NSString*)_methodDescription; @end // Somewhere in the code: NSLog(@”%@”, [objectToInspect performSelector:@selector(_methodDescription)]); Output will look as following: <__NSArrayM: 0x7f9 ddc4359a0>: in __NSArrayM: Class Methods: + (BOOL) … Read more
Matz prefers second person singular or third person plural: “responds_to?” probably makes more sense to English speakers than “respond_to?”. Maybe. But I’m Japanese. Ruby is not English. It’s the basic naming rule to avoid third person singular form in the standard libraries. you = Human.new if you.respond_to?(:knock) … end
Just pass false for the inherited argument of public_methods: “hello”.public_methods.include?(:dup) # => true “hello”.public_methods(false).include?(:dup) # => false Not an answer to your question, but in case you didn’t know, irb does autocompletion, so it’s easy to get the list of public methods (especially if you know the beginning of the method you are looking for). … Read more
Another way to user JacksonObjectMapper is the convertValue ex: ObjectMapper m = new ObjectMapper(); Map<String,Object> mappedObject = m.convertValue(myObject, new TypeReference<Map<String, String>>() {});
