You can use Java jar tool. List the content of jar file in a txt file and you can see all the classes in the jar. jar tvf jarfile.jar -t list table of contents for archive -v generate verbose output on standard output -f specify archive file name
.border-blue.background { … } is for when both classes are used together. .border-blue, .background { … } is for either class. .border-blue .background { … } is for where ‘.background’ is the child of ‘.border-blue’. See Chris’ answer for a more thorough explanation. Also see W3 Docs on CSS Combinators
The first is used to initialise newly created object, and receives arguments used to do that: class Foo: def __init__(self, a, b, c): # … x = Foo(1, 2, 3) # __init__ The second implements function call operator. class Foo: def __call__(self, a, b, c): # … x = Foo() x(1, 2, 3) # __call__
Variables declared inside the class definition, but not inside a method are class or static variables: >>> class MyClass: … i = 3 … >>> MyClass.i 3 As @millerdev points out, this creates a class-level i variable, but this is distinct from any instance-level i variable, so you could have >>> m = MyClass() >>> … Read more
A classpath is a list of locations to load classes from. These ‘locations’ can either be directories, or jar files. For directories, the JVM will follow an expected pattern for loading a class. If I have the directory C:/myproject/classes in my classpath, and I attempt to load a class com.mycompany.Foo, it will look under the … Read more
The problem is that the first argument passed to class methods in python is always a copy of the class instance on which the method is called, typically labelled self. If the class is declared thus: class foo(object): def foodo(self, thing=None, thong=’not underwear’): print thing if thing else “nothing” print ‘a thong is’,thong it behaves … Read more
Disabling content filtering The easiest solution is going to the config.js and setting: config.allowedContent = true; (Remember to clear browser’s cache). Then CKEditor stops filtering the inputted content at all. However, this will totally disable content filtering which is one of the most important CKEditor features. Configuring content filtering You can also configure CKEditor’s content … Read more
See Why in swift we cannot adopt a protocol without inheritance a class from NSObject? In short, WCSessionDelegate itself inherits from NSObjectProtocol therefore you need to implement methods in that protocol, too. The easiest way to implement those methods is to subclass NSObject: class BatteryLevel: NSObject, WCSessionDelegate Note that you are dealing with Obj-C APIs … Read more
Why would you want to do that? If you want to return some other object when a class is called, then use the __new__() method: class MyClass(object): def __init__(self): print “never called in this case” def __new__(cls): return 42 obj = MyClass() print obj
Because an instance of an inner class is implicitly associated with an instance of its outer class, it cannot define any static methods itself. Since a static nested class cannot refer directly to instance variables or methods defined in its enclosing class, it can use them only through an object reference, it’s safe to declare … Read more
